prefetch abort exception on CentOS 5.1

I would escalate that through your tech support group.  Let them know
that you see a firmware error

 "EVT#01762-06/21/08 11:50:06:  15=Fatal firmware error: Line 1014 in

and that you would like to have them push that up through their internal
escalation path(s) I will not hazard a guess as to the final disposition
of this (transient vs. permanent) I would also double check your
backups, just in case...

Subject: prefetch abort exception on CentOS 5.1




I'm running CentOS 5.1 64-bit on a Dell PowerEdge 1900 with a Perc 5/i.

It's running VMware 1.0.5.  It been running fine for about 4 weeks.  I
got a call today and the server was not responding. On the console I

sd 0:2:0:0 rejecting I/0 to offline device

EXT3-fs error on sda3 (my root partition). VMs run on same RAID5 logical
drive, but in a LVM partition.

I could not login via console or ssh. Rebooted and the server seems to
be running fine.

Found the following in the TTY_000000.log

Running the following:
Perc Firmware version 5.2.1-0067
Driver Version:

I also notice in the log for every boot I get the following regarding
the storage environment

T0: LSI Logic MegaRAID firmware loaded
T0: Firmware version 1.03.40-0316 built on Sep 14 2007 at 03:16:20
T0: Board is type 1028/0015/1028/1f03

T0: Initializing 1MB memory pool
T0: EVT#01763-T0:  0=Firmware initialization started (PCI ID
T0: EVT#01764-T0:  1=Firmware version 1.03.40-0316

T0: EepromInit: Family=33, SN=ed462f020000
T0: Waiting for Expansion ROM to load (ESC to bypass)...mfiIsr:

It looks like this problem is related to the storage driver to me but I
don't know what else to look at.  As far as I can tell all the drivers
are up-to-date.
