Windows Server 2003 SBS SP2 BSOD ntkrpamp

Hi
We have a Windows SBS 2003 SP2 on a Dell PE1900 which had a few BSODs recently.
I have run windbg for crashes on 07/01/2013 and 05/30/2013 and both point to ntkrpamp.exe but both have different strings.

Controller is Perc 5/i with RAID5
Dumps are attached.

I ran debug with Analyze and then lmnt:

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 00000004, memory referenced
Arg2: d0000002, IRQL
Arg3: 00000000, bitfield :
      bit 0 : value 0 = read operation, 1 = write operation
      bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: 8080f5f3, address which referenced memory
