I take it kernels < 2.6.23 are known to be functional? If so, a git
bisect should be really easy if you're a git user _and_ the breakage is
in drivers/ata/sata_via.c, there are only two meaningful commits
involved.
homer:..git/linux-2.6 # git bisect start -- drivers/ata/sata_via.c
homer:..git/linux-2.6 # git bisect good v2.6.22
homer:..git/linux-2.6 # git bisect bad v2.6.23
Bisecting: 2 revisions left to test after this
A full bisection would take quite a few more builds.
(I haven't noticed anybody else reporting similar troubles, and quite a
lot of time has passed since 2.6.22 was released.. that makes me
suspicious of your hardware)
Maybe you should post again, and add cc's to linux-ide@vger.kernel.org
and linux-scsi@vger.kernel.org, perhaps someone there can give you a
better idea.
