grep'ed dmesg
After I upgraded from 3.7 kernel to 3.8+ kernels, my GPU have started hanging
itself. Sometimes it recovers, sometimes it doesnt. Sometimes it recovers after
a single "kick" sometimes after 4-5 kicks.
I upgraded the Xorg intel driver from 2.20.13 to 2.21.12 because I wasnt even
able to resize accelerated windows without hangs. But it still hangs sometimes
when running something accelerated (VLC, some game).
I also get 2 new errors in my dmesg after i upgraded from kernel 3.7.
>From kernel 3.8 I get:
[drm] GMBUS [i915 gmbus dpb] timed out, falling back to bit banging on pin 5
>From kernel 3.9 and 3.10 I get:
[drm] Wrong MCH_SSKPD value: 0x16040307
[drm] This can cause pipe underruns and display issues.
[drm] Please upgrade your BIOS to fix this.
I'm running up-to-date Gentoo + a few keyworded packages on a Thinkpad T420.</pre>
