You've got a problem with drive id3 and it is causing your scsi bus to reset
and getting write errors on heavy io.  Probably need to replace the drive.

Subject: aacraid-i/o error

Has anyone had any luck getting the Netraid 4M card (aacraid driver) to
work properly with kernel v 2.4.x or 2.5.x.  Under heavy I/O I get
errors in /var/log/messages (see below).  Sometimes it causes one of the
disk to go offline and the systems Panics.

I've tried the following (RedHat distro)

Kernel 2.4.19 - get the below errors
Kernel 2.4.20 - aacraid mod will not load, hangs system
Kernel 2.5.48 - Kernel Panic during boot

In all 3 cases I'm compiling the aacraid driver as a mod so that the
scsi controller (megaraid) for disk which contains the root partition
loads first.  I'm also using evms (volume manager).  Again, everything
works fine until heavy I/O.

Any help would be greatly appreciated,
