watchdog caused traceback due to USB hang

Hi,

I've pi2 used as a headless tvheadend server with two tuners (so lots of USB traffic). Every so often (after a day or two) I get hard hangs of all USB traffic which has prompted me to manually reboot the thing.

I've now enabled the watchdog, configured reboot on panic and gotten myself a serial cable and I now start to see results.

Attached is a large log of where the USB goes south and eventually I get a kernel backtrace triggered by a watchdog codepath somehow.

Any ideas how to fix this? (grep for 'cut here' for the kernel bits)

How did you enable the watchdog? This look suspicious

Sep 22 18:06:13 rpi2 systemd-shutdow[1]: Failed to set timeout to 600s: Invalid argument

The hardware watchdog is limited to around 30 seconds I believe due the number of bits in the hardware countdown timer. Ten minutes is very long for a watchdog timeout. 10 seconds would be a more common value.

@andersthomson Please provide a lsusb -t output of the affected setup. Are you able to narrow down the affected setup to a minimum setup of connected USB devices?

watchdog is enabled as with the systemd unit, which exec's /usr/sbin/watchdog

My "is things in a stable state?" script detected this in dmesg yesterday, which also points to the watchdog.

You appear to have 4 (?!) USB hubs of various sizes plugged into the Pi. Can you post the output of lsusb -t please?

Can you also say whether these hubs are self-powered or bus-powered?

lsusb.txt

Two self powered hubs off the pi2, one of them is a 10 port with carries three 4way splitters internally.

I got the hubs in an attempt to rule out power issues as I have to (supposedly power hungry) TV tuner sticks in there.

Can you try again after running rpi-update? There have been some bug fixes that may affect your use case.

I'm compiling my own stuff. Can you indicate git commit and config to use?

Thanks! /Anders

He'll be referring to top of rpi-4.9.y tree (currently https://github.com/raspberrypi/linux/commit/9a5f215eda12bad29b35040dff00d0346fe517e2) and using the bcm2709_defconfig. See: https://www.raspberrypi.org/documentation/linux/kernel/building.md

But it is more useful for us if you test with a default kernel. Reporting a bug with a custom built kernel adds another level of unknown when we try to diagnose.

Building that commit against that config right now. As it happens, I'm on rpi-4.9.17 right now, and cannot recall seeing the Watchdog in the oops for quite some time. I do still get regular oopes from the usb otg driver though (and an attempt at vanilla-4.11 with dwc2 consistently fails to get the tuners operational)

@andersthomson Could you please explain what goes wrong on dwc2?

So, for what its worth. Freshly compiled. Not sure where this oops is pointing.

Can you try again after running rpi-update? There have been some bug fixes that may affect your use case.

@andersthomson are your own builds less stable than rpi-update ones?

Long story. I've had continuous issues with the rpi kernel and the two tv dvb-t2 dongles I have. Oopses related to the otg driver. Apparently upstream devs won't touch it in favor of the now mainline dwc2. Reports elsewhere suggested that the dvwc2 driver has issues with isoc transfers though (and the tv stuff uses a ton of it I understand). Anyway, I've compiled a vanilla 4.11, enabled the dwc2 and got the dt sorted (methinks).

The net result is that it boots, tend to have a few hiccups when probing, finding my two disks/serial cards/two tv cards, but moves on into operation. The TV stuff fails to come up though. No life from it and a stream of i2c errors (during mux scanning, I guess). I kind of hope that I'm missing a module or something, as this happens right after start.

I'll grab a log once I can get the tv grear from the family.

Historically no difference. I started out grabbing the kernels etc from the rasp github tree manually, and they fail in the same way (gentoo here, so no rpi-update.) In an attenpt at being able to (help with) debuggning the thing, I've moved to compiling it myself (and there was the odd config I wanted to change), and eventually move to vanilla.

I've been through two rpi2 about 5 power adapters and got myself two self-powered usb hub to remove power issues. No difference. USB related oopses one way or the other...

Alright, here's a boot log of vanilla 4.11.1. I've no idea what causes the i2c errors, but it's consistent on each boot, and I guess timed with tvheadend starting to do its thing. Tvheadend shows no evidence of the DVB adapters doing any good.

Ideas?

Historically no difference. I started out grabbing the kernels etc from the rasp github tree manually, and they fail in the same way (gentoo here, so no rpi-update.) In an attenpt at being able to (help with) debuggning the thing, I've moved to compiling it myself (and there was the odd config I wanted to change), and eventually move to vanilla.

I've been through two rpi2 about 5 power adapters and got myself two self-powered usb hub to remove power issues. No difference. USB related oopses one way or the other...

@andersthomson https://github.com/andersthomson are your own builds less stable than rpi-update ones?

@andersthomson In order to keep track of this issue i suggested to open a separate issue for dwc2. I'm interested to get as much as possible dwc2 issues fixed, but unfortunately i'm no USB expert. It would be helpful in narrowing down the issue, if you reduce the affected device to only 1 device per test. So you could make a good / bad list. I also tried tvheadend, but it's too complex for debugging. Aren't there any simpler commands?

This is on vanilla kernel, so an issue on rpi's github would be out of place, right?

The testing I've done shows that all the USB devices are working find under dwc2. Well, at least the disks. I've not yet tested the serial devices (one card reader, one tellstick home automation dev). But no signs of complaints there.

DVB cli commands are scarce. I've tested scan-dvb from linuxtv-dvb-apps, but it didn't go anywhere either (same i2c error, no forward progress shown).

I'll make another scan-dvb run and see if I can correlate i2c error with the syscall stream.

Yes, the mailing lists linux-usb or linux-rpi-kernel would be the right place. But i usually didn't expect so much motiviation. Would be nice if you could provide your scan-dvb cli calls.

Is this issue still valid on latest kernel?
