Created attachment 112185 [details] content of /sys/class/drm/card0/error According to the instruction in syslog, I'm sending the content of /sys/class/drm/card0/error . I'm using debian sid.
Death on a MI_FLUSH after a pageflip + seqno write. Unusual.
I've seem something similar yesterday... I guess on gen2 (#75957)
I think I know what causes this problem -- I had the following kernel parameters set in extlinux: i915.enable_rc6=7 i915.lvds_downclock=1 i915.semaphores=1 i915.fastboot=1 I removed them from the kernel line because the problem started to occur 5-10 times a day. I don't know if one of the parameters is to blame or all. I just used them for power save mode, at least that's what they said on the internet. Anyway, now I don't get the error.
Mikhail, we consider changing i915.enable_rc6 or i915.semaphores from their platform specific defaults unsafe. I'm closing the bug, if you can reproduce without the parameters, please do reopen. Thanks.
