which machines have you tried?
Comment 2 WuNian 2008-08-03 18:05:27 UTC
We tested on G33.
Comment 3 Wang Zhenyu 2008-08-04 18:01:09 UTC
oh, this is known broken issue. Patch is there, but there's compat issue to handle. We might push this to OSVs first though.
Comment 4 Wang Zhenyu 2008-12-02 22:36:09 UTC
Brandon Philips's patch is on agp-2.6 tree now, and should be in next kernel release.
