Hello,

I have two of the same servers running 8.1 (just upgraded from 8.0) amd64.
I run ZFS so I just run the drives as JBOD (well, the closest thing to 
JBOD this
controller can get, a bunch of 1-disk raid0's). I just wanted to say 
that I haven't
seen any errors like you describe, maybe they only appear when using the 
PERC
raid functionality, or perhaps the disk really is going bad. My servers 
are close to
going into production so any testing from my side will have to be 
without destroying
filesystems, but let me know if you need anything :)

Regards & good luck,
