| |
Hi,
I've also been seeing the AMD-761 + radeon total lockup when X starts, as described in
http://sourceforge.net/tracker/index.php?func=detail&aid=221904&group_id=387&atid=100387
The X server fixes from ATI seem to fix this when running without dri, but in dri mode, I still see the lockups 75% of the time. However, the fix described above and appended below appears to be a complete cure for me so far.
I'd like the opinion of the DRI folks about whether this should be in the mainline kernel DRM, or if this is just a workaround for a problem that still needs fixed elsewhere, but it certainly appears to work fine for me.
