Try 2.6.22-rc4-gitX...
Is there a patch in particular I can maybe apply? I see you made a
couple of commits ... my problem is this is also happening on one of my
production boxes which has a few other patches applied, I'm a bit scared
of conflicts ... I don't really want to break anything by upgrading the
kernel.
The two most relevant git commits:
commit 51b94d2a5a90d4800e74d7348bcde098a28f4fb3
Author: Tejun Heo <htejun@xxxxxxxxx>
Date: Fri Jun 8 13:46:55 2007 -0700
sata_promise: use TF interface for polling NODATA commands
commit 464cf177df7727efcc5506322fc5d0c8b896f545
Author: Tejun Heo <htejun@xxxxxxxxx>
Date: Sun May 27 15:10:40 2007 +0200
libata: always use polling SETXFER
If you have a git tree local to you, "git-diff-tree -p $COMMIT" will
extract a patch, otherwise click "raw" after surfing to
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=$COMMIT
