This bug is primarily to ensure that the 2nd patch (now in linus' tree: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=cf2aff6eff251b6fbdaf8c253e65ff7c693de8cd) either hits stable or is carried in Fedora until it does.

Comment 1 Joshua Roys 2011-11-14 01:16:19 UTC

I built a f16 install dvd with a patched kernel (the 2nd patch in the fdo bugzilla and two other patches it depends on) and I now have KMS.

upstream:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b4f15f808b9a79b6ad9032fa5f6d8b88e1e1bf11
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=1d33e1fc8dcce667a70387b666a8b6f60153d90f

According to the FDO bug, this will likely affect (many? some?) AMD-based laptops.  It would be nice to have this mentioned in the Fedora Common Bugs.

Comment 2 Josh Boyer 2011-11-14 14:23:18 UTC

Dave, if the patches from comment #1 are something that should get brought in, let us know.

Comment 3 Joshua Roys 2012-01-03 14:43:13 UTC

These patches seem to be included in 3.1.6 as per http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=shortlog;h=refs/heads/linux-3.1.y .

Comment 4 Joshua Roys 2012-11-29 18:53:53 UTC

This has been fixed for a while.  Closing.
