Mutterings:
Well I set the BIOS down to 160 and turned off Packeting and QAS and let
that run for a day
( http://ftp.linux.org.uk/~bryce/scsi-bios.gif )
Unfortunately the driver has blown up in a different way now.
I'm at a bit of a loss as to whats going on as the disk verifies
fine from the adaptec bios utils
I've now set the speed to 80 so we'll see how this goes though it's a shame
to loose the performance as a result in the drop (was 71MB/s now 61MB/s)
