[SLUG] SCSI disk problems


All,

I've got a linux box - RedHat 6.1 base, 2.2.16 kernel with nfsv3 patch
I'm using the aic7xxx SCSI driver for an Adaptec AIC-7892 Ultra 160/m
adapter.
I've got 1 20Gb SCSI drive (ID 0) Seagate ST318436LW
I've created one partition for the whole disk.

I'm getting the following sorts of messages in my syslog:

-----

Unfortunately I don't know enough about SCSI drives to know what's going on
here.
Can anyone tell me what's causing these problems?
Is the drive dead?
Is there a bug in the driver?
Is it because I've created too big a file system?

Any help is appreciated.
Thanks.
Tony...
