dmesg
Can you reproduce easily? if yes - please record tracing: sudo trace-cmd record -e iwlwifi -e iwlwifi_msg and send the trace.dat file. Thanks. Not very easily. But it seems that I'm getting it pretty often under high CPU load. I'm recomiling kernel with CONFIG_IWLWIFI_DEVICE_TRACING. Will back tomorrow. Created attachment 152741 [details]
trace.dat
Now it's 0x88, but everything else seems to be ok. Now I'm almost sure that it happens only under load.
PID 3770 is wpa_supplicant.
Attaching trace.dat.

Thanks - I think I understand what happens here - but I need to ask someone who is currently not available. I'll report back. For sure - this WARNING is noisy but harmless. Oh - and this frame seems to be send by the supplicant (if the trace is to trusted). Yes - this seems to confirm what I think. I confirm this bug. Hardware name: Dell Inc. XPS13 9333/0GFTRT, BIOS A04 03/19/2014 Sorry - due to the merge windows closing, I am shuffling my tress all the time - so the commit ID can't be trusted. Just take my -fixes tree if you want to test the fix. |
