@malacalypse your problem doesn't look related to this issue. Probably best to start a new issue.
This makes me so happy, great work guys! I'm going to update and see if I can validate this fixes my issue.
@P33M Do we know when this issue was introduced? Looks like it's been there from day one?
Is it confirmed that this issue won't affect 4.9.x kernels? I have a number of systems still using Jessie.
I can also confirm that the issue is now solved with the latest kernel. I had not a single error since the update. Thanks for the fix!
It's a regression in 4.14, not present in 4.9 - https://github.com/raspberrypi/linux/commit/aa3c8cd4ea9e49269e0c0e1072c0b91c7b49e14e#diff-1d4760cae1bb22f857c0b933bd6c5900
Wierdly, I was positively testing this new path as a fix for another issue so the copy-paste fail must have happened while cleaning up the patch.
Closing as fixed
Still broken for me as of 4.14.72
@mypiandrew same here
Define "broken". Have you seen a recurrence of "Mode Mismatch Interrupt" messages appearing in the kernel log since this patch was pushed?
No. Broken as described in https://github.com/raspberrypi/linux/issues/2692
@P33M No, none of the int 68 stuff, it's still a mess of errors with devices not enumerating correctly though
I've commented to #2692 as that seems more clean than keeping this going
I'm in the UK so if you want me to mail you some test hardware (assuming that helps you) we can arrange that.
I'd like to add something in. Y'all are all steering towards USB power related issue. I am currently getting this issue, and have found a read this thread all the way through. So I unplugged devices and tried to boot. Doesn't help anything. Here's my other problem. After passing all those errors in boot (the 2 out of 10 times it does pass them) I then get a black screen with my pointer arrow glitching in and out even tho no devices were connected). Instead of it loading the login screen, it gets stuck there. Just glitching away So I cannot try other fixes.
I have tried plugging keyboard in AFTER passing boot and getting this screen. I tried crtl + alt + F1, and saw the terminal version pop up for a quick second before glitching out again back to pointer screen. (When plugging in, it does show power logo now though) I have tried logging in with keyboard on the messed up login splash, to see if it'd let me in. Nothing.
Looks like an issue with dwc_otg was introduced with 4.14.x versions - 4.9.80 does not show issue.
When booting RPi 3, 2 or ZeroW with 4.14.x versions with a "C-Media Electronics Inc. USB PnP Sound Device" connected** get the following boot messages (extracted from dmesg):
Tested and errors with 4.14.18 (and 4.14.22).
Back revved to 4.9.80 where the error messages do not show:
** note: the "C-Media Electronics Inc. USB PnP Sound Device" is actually embedded in a 4-Port HDMI & USB KVM Switch (this one from ModMyPi) - there is a push button switch to turn off audio which disables the Sound Device - the RPi will then boot without error (but then no sound..)
