5 years ago I‘ll investigate this on the next occurrence. Anything else I could check or collect in that situation?

Needed to reboot the system now. Would at least be great to know if there´s another workaround besides the reboot - or to find a solution of course.

The module lan78xx.
sudo rmmod lan78xx && sudo modprobe lan78xx
I use my Raspberry to load roms to an arcade machine (Sega Naomi) through ethernet wire. With the first version of Raspberry Pi it works perfect but with Raspberry Pi 3 B+ sometimes Ethernet simply stops working and after many hours investigating the only (easy) way to restart the communication is "restarting" the module lan78xx. I assume the problem is the module lan78xx.
Hope it helps

Oh sorry, this error is because the driver lan78xx is kernel builtin. To solve this, I recompilated the Kernel configuring driver lan78xx as a module in the .config file. If you are interested in recompile the Kernel follow this guide: https://www.raspberrypi.org/documentation/linux/kernel/building.md (you need knowledge about Linux).

5 years ago Sorry, I am looking for a solution and as a user with some (!) technical knowledge the compilation of a kernel is definitely out of my comfort zone.
What else can I do to help others helping me? I ran out of ideas and need to fully rely on other users‘ knowledge :-(
I mean... it‘s a bug, right? Some usb timing issue in the lan78xx module I assume. How to fix it?

5 years ago Who knows where the bug is. It takes so long to replicate it will be impossible to debug without finding a quicker way of reproducing. Something is clogging the system or taking much longer than expected, causing the workqueue system to give this error. But it's so rare its going to be some weird timing issue somewhere, perhaps related to packet content to size, and could be in the lan driver or elsewhere. Very difficult to fix so if anyone can figure out a way of replicating it reliably, that would make things a LOT easier.

5 years ago We are diskless booting an archlinux installation on a PI 3 B+, and with the latest kernel we are ketting the
lan78xx 1-1.1.1:1.0 eth0: kevent 0 may have been dropped as soon as the root file system is mounted on nfs and it starts booting, happens every time in our setup. Only by downgrading, (We used the latest 4.14 kernel, does it boot without the error).
We are using tftp for the firmware, kernel and initramfs. And nfsv4 for the root partition.

5 years ago After 23 days of uptime it happened again one hour ago. Needed to reboot as there is no other workaround. No load on the USB interfaces by the way, but on the ethernet interface instead.
It´s a neverending story... hell I´m happy to replace this peace of shit by the new Pi 4 which hopefully will have another implementation or at least segregation of ethernet and USB lanes, finger´s crossed.

5 years ago It practically impossible to debug an issue that open happens every 20 days or so, so really no idea how to progress this. Without some indication of what is causing it, or a simple way of replicate it, it's so so difficult. What is odd is that is it not being reported by many others, which sort of indicates HW either onboard, or in your environment. But again, who knows.

5 years ago If you haven't anything else to do, I recommend you recompile the kernel and enable the driver lan78xx as a module, instead of built-in in the kernel.

5 years ago Once (sometimes twice) per day my Raspberry Pi 3B+ suffers from this too (kevent 0 may have been dropped)
Result is that eth0 shuts down completely. When monitor and keyboard are hooked-up, I can do a reboot from the CLI otherwise unplugging and replugging the powercable is the only solution.
What can I do to help someone debug this particular issue?
The RPI is hooked-up with an official adapter + cable, wifi and bluetooth are disabled (as well as most GPIO related features that can be tweaked using raspi-config). System is otherwise up to date.
The RPI functions as a DNS server in the local network and has no other peripherals attached (except when debugging, then a monitor and keyboard are attached).

5 years ago This is much more frequent than any other reports, which can goes weeks without it happening. Not sure how you would go about doing it, but a wireshark trace around the point where the kevent problem fires might be useful. I suspect this is some sort of packet/set of packets on the network causing something to go slowly, causing the handling of the kevent to be delayed, causing the next occurence of the kevent to be dropped. You could probably have a script running dmesg -w | grep kevent or similar that causes wireshark to save its trace for the last few minutes. I'm not familiar enough with wireshark to know how to do that bit, if indeed it's possible!

5 years ago Well, I'm certainly open to applying a patch and testing it... Problem is I wouldn't know where to start. Anybody able to build this patched kernel which I then can (somehow) install on my RPI??
All I can tell, for now, is that my RPI 3B+ has a temperature of 53,6°C with a load average of 0.15 / 0.13 / 0.11 when the network decides to stop working.

kernel7.img must be copied to boot partition and the rest must go to rootfs.

5 years ago This time around the entire RPI froze.. I do have a picture of the last dmesg output (there was no "kevent 0 may have been dropped" on those last few lines... Only a few stacktraces). I will try to type a summary of it later today.

The patched kernel would most of the time end up with the "kevent 0"-problem, but sometimes would freeze entirely. Currently running the latest (unpatched) kernel again. Problem stull occurs roughly once per day, and as a stop-gap I've connected the rPi to a smart socket which allows me to remotely pull-the-plug. Since so few people seem to have this problem, I'm somewhat thinking it is some faulty hardware. I'm going to try to get mine replaced or fixed... and if that fails (hope not), I'll consider an rPi4 with some actively-cooled case.

5 years ago @Corvo Could please describe your setup of the Raspberry Pi 3B+ (connected devices, running services), so we might have a chance to reproduce it?

5 years ago @lategoodbye I'm running an up to date Raspbian Stretch install on the rPi3B+. Besides the default packages of Raspbian, I have installed:
openjdk-8-jre-headless packages to be used with an install of the Ubiquiti UniFi controller (unifi package from the official repository)haveged packagecurl -sSL https://install.pi-hole.net | bash method)( To be more precies, I've followed this how-to guide )
The install is configured to use a static IP.
The PI is connected to a non-PoE port of a UniFi switch. No other peripherals are connected. The rPi is powered by the (starter kit) official plug.
If you need more info, let me know.

Aug 1 23:19:30 raspberrypi kernel: [211737.052874] lan78xx 1-1.1.1:1.0 eth0: kevent 0 may have been droppedIt happened after copying/streaming a lot of data from/to the HDD attached to the Pi during the last two days. It seems like it (ethernet port, USB port or lane between them) either is only capable of a certain amount of data (few gigabytes) or it´s a temperature thing. This is the only thing I could imagine, would probably explain the different time spans between the incidents.

4 years ago Update: Pi 4 hardware is running constantly and stable for more than 32 days now (a time where Pi 3B+ hardware would´ve crashed already at least once, the usually time was about maximum 21 days) I assume it´s a 3B+ specific error - which I really don´t care anymore, I spent so much time on this **** of crappy hardware - I´m very happy with the extremely fast Pi 4 now. As it´s not really fixed I don´t want to close the issue though.

4 years ago There is en entirely new ethernet controller on the Pi4, so this is unsurprising. The new controller will have its own weird issues, so no need to include this one!

4 years ago There has been some recent movement/changes to the lan78xx driver that may have some impact on this on the Pi3B+. Once they are merged I'll flag it up here. If you are happy to build you own kernel etc then let me know and I can post links to the patches.

4 years ago Actually, will probably be in rpi-update in the next few days, as we have merged them to our github tree. So you can wait for that, or just get the latest tree and build it.

2 years ago I am also having this issue on 5.15.32-v8 on a 3B+
Symptoms:
It happens pretty randomly. In some cases it happens when transferring a significant amount of data using the Ethernet interface, but not every time.
Similar issues: https://github.com/raspberrypi/linux/issues/2447 (different Kernel Event, Same Chip) https://github.com/raspberrypi/linux/issues/2027 (different Chip, Same Kernel Event)
It‘s really freaking me out especially nobody‘s looking into this so far and the issue linked above with the same kernel event on a different chip is quite old and STILL not fixed. So after the memory leak my Pi 3B+ was suffering on kernel 4.19 line for MONTHS and has been „fixed“ at the end of March in 4.29 kernel update this is the next issue keeping my system from being reliable.
Possible relevant information:
Kernel currently (already happened on earlier versions of 4.19 path): 4.19.30
