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?

No.  This system and the drives pre-date NCQ.  I think NCQ is only 
implemented in SATA and these are IDE drives.  Sometime over the 
weekend, I am going to reload SUSE 11 and try to do some more debugging.

BTW: It's back to 10.3 (kernel 2.6.22) running happily with a VMware 
server thrashing away at the disks.

This has recycled back to the top of my todo list, I have a server in 
mothballs with IDE drives, I'll pull it out, upgrade to FC9 current 
(non-rawhide) and see if I have any problems. It's off due to lack of 
need, not really obsolete, so it's a fair test. O'll put a dew hundred 
GB of raid-1 and beat on it.
