Unable to add attachment of error log.

> Unable to add attachment of error log.

Why unable? Please notice that since this is a sysfs file, some tools cannot properly work with it. I recommend you to "cat /sys/class/drm/card0/error > /tmp/error.txt", and then manipulate the /tmp/error.txt file as usual.

Also, the next time you reproduce this bug, can you please attach the full dmesg output? It's even better if you're able to boot with drm.debug=0xe as a Kernel parameter before reproducing the problem.

Can you reproduce this problem consistently?

dmesg with drm.debug=0xe kernel parameter

This is the full dmesg output immediately after the crash occurs. drm.debug=0xe kernel parameter was set at startup

GPU crash dump

GPU crash dump that was saved to /sys/class/drm/card0/error

I am having the same problem as well. The bug can always be reproduced by viewing a video on Youtube using Google Chrome. I have attached the dmesg output (with drm.debug=0xe) and the GPU crash report that was generated

I have exactly the same problem.

Reproducible always by playing a single video on youtube in chromium browser.

P.S. I'll add a crash dump

GPU crash dump on the Gentoo machine

Gentoo kernel .config file

What's your Mesa version? Can you try updating to 10.4.3+ or 10.5+. Those should have some gen4+chrome hang fixes.

Also if you update your kernel to 3.19+ then the GPU reset should actually work, and so you wouldn't need to reboot after each hang.

I've updated the system from mesa-10.3.7-r1 to mesa-10.5.6. The problem seems to be solved. Will test for several days.

Thanks!

Please reopen if still seen with mesa 10.5 or later.
