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?
