Ever since I've upgraded to RedHat 6.2
My raided scsi drive has had questionable integrity.
The drives were setup to store my extremlely busy
(read and writes) mysql database tables.
My main system is mounted on an IDE drive.

Since the upgrade to the redhat 6.2 I constantly
getting kernel panics by various programs including
kswapper and raid1d. To quickly fix the problem I booted
my machine off the Redhat 6.2 rescue disk and
copied my data from the raided /usr/local/var to the main ide disk
(/usr/local/var2).
The difficult part is that there are so many peices that I have to
look at. I suspect the adaptec 2940uw card or the aicXX driver.
Machine has been running fine since I made the above changes but I really
want to find the problem(s) so that I can go back to my raid1 setup which
I was previously happy with.
Sorry for the sparse details, but I will keep everyone up to date as I
work on this problem.
Thanks
Below is the last kernel panic caused by raid1d:
