Bug ID: 85087 Summary: [NVD9] Thinkpad T420 - freezes under load Product: DRI Version: XOrg CVS Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: major Priority: medium Component: DRM/other Assignee: dri-devel@lists.freedesktop.org Reporter: david.heidelberger@ixit.cz

Dist: Ubuntu 14.04 Kernel: 3.13 - 3.17.1 Mesa/DDX: Ubuntu default - oibaf git generated Setting: to discrete GPU (PRIME disabled).

When loading Nouveau or in third icon of KDE loading (probably kwin load compositing) it froze. No SYSRQ, no ssh working. It's completly frozen.

It's not my laptop, so i'll try proviede debug information, but it will take time.
