Created attachment 47721 [details] Xorg.log Hi I use linux kernel 3.0.0-rc2 with intel xorg driver build from git and sometimes X hung and I can't do anything. Couldn't check if this was only X server hung or whole system because I didn't have other machine to try to login on hang laptop via ssh. I've attached Xorg.log and kernel.log. Please let me know if I should provide some more information to help in investigation of this bug.
Created attachment 47722 [details] kernel.log
Can you please attach /sys/kernel/debug/dri/0/i915_error_state after a hang?
I'll try after next hang
Should I compile kernel with any specefic debugging options to get this paramenter?
You will need to compile in CONFIG_DEBUGFS and then mount -tdebugfs debug /sys/kernel/debug
Created attachment 48050 [details] kernel.log_with_drm_debug Still can't catch this issue and be able to look at debug fs in same time. But attached kernel log with enabled drm debugging, may be it will help in investigation
Seems I can't catch it because the whole system hangs along with GPU and I can't ssh on it to check the debug fs
One last thing to try before resorting to netconsole and hoping that it is an ordinary OOPS... Can you please add i915.reset=0 to your kernel boot parameters and cross your fingers?
Looks like a mixture of everything here. Let's start by assuming that it is one of the semaphore/rc6/fbc issues, and update the kernel.
Ping. Please retest on kernel 3.4-rc.
Reporter is awol, presumably this is fixed with all the latest workarounds ...
