I just wanted to point out that this issue appears to have been fixed by a one-line change to the sata_mv kernel source by Mark Lord. Discussion is here towards the bottom of the bug report page:
https://bugzilla.redhat.com/show_bug.cgi?id=462425
And the patch itself is here:
https://bugzilla.redhat.com/attachment.cgi?id=329048
I haven't confirmed that the fix works yet. Reportedly with the fix in place, you can safely re-enable your disk write cache.
