Hi, I have been experiencing frequent (~1/day) freezes of by box (Acer Travelmate 5720, intel GM965/GL960), with 2.6.36-rc1+ (vanilla, Linus' tree from git). I could only manage to capture one oops at one of the freezes, and traced it back to the i915 driver (I guess). Can this trace help you at all? Is there a known issue or some steps I could take to help you tackle it? A git I could pull experimental i915 code to test from? Please CC: me. Userspace: Mandriva 2010.1, X 1.7.7, kde 4.4.3 (sucks, many display artifacts). Thanks -- Say NO to spam and viruses. Stop using Microsoft Windows!
