Hello Denis,

I attached the glxinfo as per you requested.

Today I got another crash while resuming after suspend. Here is the only output
I got from dmesg:

[10081.255459] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU
pipe B FIFO underrun
[10081.335164] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU
pipe A FIFO underrun


gdm couldn't restore the session and it was like a login loop. I was able to
see the login screen but the session was hanging after I enter my password. I
tried to kill all open gdm sessions and restart the service but no luck. I got
the same errors when I restarted the gdm 2 times. Then I rebooted and the
problem was gone. 

As I mentioned in my previous comment I started using optirun with the apps,
such as chrome, which was causing i915 to crash but nothing changed. Chrome was
running on dGpu before I put the device into the suspend mode.
