Dell 1950 Crashing Intermittently Event ID 2336

I have a old PowerEdge 1950 Server that I'm trying to repurpose.  I have gone through and attempted to make sure that the BIOS and any underlying hardware firmware have been updated.  I've installed Server 2012 R2 and there is an AV running.  When the AV does a daily quick scan the server will intermittently crash and records the following errors.

Event ID 41 - Kernel Power

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Event ID 2336 - Server Administrator

Controller event log: Fatal firmware error: Driver detected possible FW hang, halting FW.
: Controller 0 (PERC 6/i Integrated)

Controller event log: Fatal firmware error: Line 3622 in ../../raid/1078dma.c
: Controller 0 (PERC 6/i Integrated)

I've tried contacting the AV vendor and they weren't much help in resolving this issue.  I have the same AV running on other servers with 2012 R2 and haven't had any similar issues.  At the moment I'm not sure if the AV is causing the server to crash or if I've missed updating something on the hardware level that's causing a conflict.

Any suggestions are appreciated.

Hello.

These errors are common with RAID 1 and RAID 10 arrays that are set ot write back mode in which  any cache lines associated with the area of correction are locked by the patrol reads. At the same time, the cache lines show that they need to be re-written back to the disk. The write will not be completed by the controller and thereafter the controller becomes unresponsive resulting into a fatal firmware error. Were you able to successfully apply firmware update for the PERC 6/i controller? If so, a res-start is necessary in order to clear any existing cache lines incorrectly flagged as dirty after a re-write failure. If not, consider doing so; else temporarily disable controller Patrol Reads as temporary solution.

Robert,

The server is currently configured in a RAID 5 with a hot spare.  I updated the PERC 6/i firmware a few months ago to version 6.600.21.08 and the server has been rebooted many times since then it my attempts to resolve theses errors.  I've updated the BIOS version 2.7, the Baseboard Management Controller to version 2.5 and the hard drive firmware to version FS66 as well.  The server seems to be stable until the daily AV scan runs in the early AM and intermittently crashes during the scan.  I haven't seen this issue outside of that scan window so far.  Is there anything besides those hardware components I mentioned that I should be updating?
