I did the upgrade last night. Drive performance was SLLOOWW. When it
came time to the reboot, I had a corrupted disk. (Not certain if that was
the fault of the upgrade. I have to finish the fsck repairs first.) And
this is with ext3. Not good.

I have been seeing real bad driver performance on the latest FC6 kernel as
well.
