Wonder if hardware or software is happening, sounds like an 
mishandled hardware error, but I'm guessing. I have a server with 
RAID1 and Fedora 2.6.22.14-72.fc6PAE kernel, up 72 days, no problems.

2.6.22 is running fine.  The problems are in the 2.6.25 kernel (FC9 
and SUSE 11.0)

Given heavy 2.6.25 use, my guess is still that the root cause of this is 
hardware, and that the change in disk code either triggers the hardware 
problem, or handles it differently. Are you by any chance running NCQ on 
your system?
