Description onorua 2015-08-17 07:59:04 UTC

Hello, 

currently have:

Kernel: 4.2.0-rc6
OS: Debian 8 (Jessie)
xserver-xorg: 1:7.7+9
Hardware: ThinkPad X1C3

I've faced a strange issue with random screen blanks and completely unresponsiveness of my system after upgrade to rc6 from rc4. I could find following strack trace in the logs:

in case you need more info - just let me know, I'll do my best to debug any things out, just tell me what to do.

can't reproduce it with 4.3.0-rc2
