Nikolay, unfortunately to be able to investigate and re-produce the issue we will need to get crash dump and also kernel log. thanks Well, I understand that, but what should I do if system completely freezes after this event? Freezes as in 'mouse not moving, keyboard doesn't respond'. Is there any way to unfreeze it to take that crash dump? Is there any way to make it make a dump automatically when this happens? Can you perhaps ssh into the machine? If this is not possible, you may also consider to redirect the console via net or serial (changing on boot command line in grub) After the laptop got frozen it doesn't ping anymore, so I cannot ssh to it and I do not think I'll be able to use network console either. Unfortunately I do not have equipment to make serial connection with laptop :(. (In reply to yann from comment #7) > Jani, is there any possible link with bug 95007 ? I don't think so, but I'm not 100%. Just to add to additional report: this seems to be happening once in a few days. And anecdotally this may be triggered more often when some animated gif is left spinning on the screen in FF.

If this is occurring, can you try to change driver in your xorg.conf Section "Device" Identifier "Intel Graphics" Driver "intel" EndSection by Section "Device" Identifier "Intel Graphics" Driver "modesetting" EndSection and then confirm result. It's a skylake, make sure you have the most recent DMC (older firmware causes GPU hangs), and the most recent kernel (4.7+, older kernels are missing w/a). There are no known GPU hangs in -intel. Hi. Thanks for your responses. Indeed I didn't see this hang for quite some time now and I do not really know what fixed it. I use stock ubuntu kernel (4.4) and oibaf drivers. I guess this can be closed for now and I will post more comments if this hang happens again. Thanks! |
