dmesg 1

Dave & co: Another Fusion problem on my E35M1-M PRO setup... With Git of all major components as of few days plus the kernel with the Fusion fix talked about a few days ago, Warsow and Padman at least are crashing on load, 100% reproducible so far for me (OpenArena though runs fine, haven't tested anything else yet). Two example dmesg outputs attached, plus one with drm.debug=15.

attempted fix.

This seems like a regression since Jerome's "fix".

attempt 3  to fix VRAM size and hopefully this bug.

try to limit vram size alternate method.

Just got around to test the 2.6.38 final kernel and the system ends up going down completely - Padman loading screen -> blank screen for ~2 seconds -> BIOS screen as the system just restarted. That's when launching Padman or related games where previously there was this TTM issue.

http://www.phoronix.com/scan.php?page=article&item=amd_fusion_fixed&num=1 suggests this is fixed, unless I'm missing something.
