X.0.log that works(i.e, DRI disabled)
This is the X log when DRI is disabled. Could someone tell me how to dump X log in a totally black screen? ;) I wish the dmesg and this X log could do some help.
You should be able to see previous X logs in /var/log/Xorg.0.log.old or something like that. Created attachment 18396 [details]
X log when dri enabled
This problem can be fixed by simply revert: commit edc6f389f6ae9cb7621270a8ddbb1892bd8df125 "radeon: fix PCI bus mastering support enables." As Alex is the author of the commit, I add CC to you. Would you please see what is going on here? there was an error in the logic. should be be fixed by these commits: http://cgit.freedesktop.org/mesa/drm/commit/?id=848f00d77381d8b442c096476302796f8fe122fa http://cgit.freedesktop.org/mesa/drm/commit/?id=e1372f67274baa44419e000f5d3d6b2e81be2b51 What exactly do they apply to? they are against the upstream drm git tree, but should apply pretty trivially to the kernel as well. I think the problem get fixed by the commit: 4e270e9b8a9d246290f3901f1fb6c5efdb734ddf drm/radeon: fixup further bus mastering confusion. at least it works well on my box ;) So I will close this entry. Thanks Alex Deucher. |
