A laptop sometimes hangs with GPU reset or might lock completely especially if I leave it turned on in sleep state over night. I'm not sure if it is the same issue because can't read dmesg output, the system doesn't react neither on sysrq nor ctrl-alt-f2, simply a blank screen.

I tried to add "intel_iommu=igfx_off" to kernel options without any luck, the issue still persists.

1. What version of Mesa are you using?
2. Do you have a HD 400 or HD 405?

(running "glxinfo | grep Mesa" should give you the answer to both questions)

/home/user$ glxinfo |grep Mesa                                                    
client glx vendor string: Mesa Project and SGI                                    
    Device: Mesa DRI Intel(R) HD Graphics (Cherrytrail)  (0x22b0)                 
OpenGL renderer string: Mesa DRI Intel(R) HD Graphics (Cherrytrail)               
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.3.7                
OpenGL version string: 3.0 Mesa 17.3.7                                            
OpenGL ES profile version string: OpenGL ES 3.1 Mesa 17.3.7                       

Attached a whole glxinfo output just in case.

Some more info that might be related:
 - I use UXA as an acceleration method in xorg.conf, SNA flickers all the time.
 - Maybe it is just a coincidence. The first hang or lock usually occurs after some time swap started to be used (I use only zram as a backend).
