The original cause of your failure appears to be OOM condition on your system, which we recover from poorly. Valid bug, and not one we'd see in development testing since we keep a lot of RAM in our systems. Also one that'll go away with KMS. However, for getting testing results without a bunch of false negatives, you'll want to populate the system with more than 512MB.

Good. case glean/fbo fail on this machine is not surprising, as it has been failed on all platforms, which needs a separate bug. Eric, I'm increasing priority since we've approaching Q1 release cycle and we need be strict for memory usage (considering there are still some old laptops and new netbooks using 512MB). hi, we retest it with 512M memory and the latest driver.kernel oops has gone now. following is the commits: Libdrm: (master)a6dd0afa87558a670f970e61b023f45a396539eb Mesa: (mesa_7_4_branch)b65bfde84d2f0d83a432602cda425a63560e4034 Xserver: (server-1.6-branch)60c161545af80eb78eb790a05bde79409dfdf16e Xf86_video_intel: (master)14bb61e0c2e28725a2f6167d3263649bc845be18 GEM_kernel: (for-airlied)edde72a59461d766997b469f6d20afdf5fe9b5b4 Good, so I'm closing this. Let's keep 512MB on this machine to see if it can find other issues caused by low memory. |
