Comment 1 Lakshmi 2019-07-16 07:54:06 UTC

Lionel, Can you please attach the full dmesg from boot with kernel parameters kernel parameters drm.debug=0x1e log_buf_len=4M?

Apart from this warning, is there any other impact?

dmesg

Kernel command options at the top of the file.
Not sure whether this is related, but I lost the wifi network at the same time this warnings happened.
Wired network still worked, display/3D was fine.

Unfortunately I always forget to add the option when rebooting a new kernel...

Isn't there enough information from the backtrace to figure out what's going wrong?

@Lionel, Do you still have the issue? 
The impact remains same as last time, you lose wifi nework when connect the machine to dock? Any other impact?

I can't repro anymore. Let's close?
