oops on P4 i875 w/ 2 gig RAM

[Magnus Stenman]

Hi!

I realize it's 2.6 time but this problem is driving me nuts. I've 
searched LKML, RH bugzilla, Google, etc and cannot find a resolution.


Machine has a Gigabyte GA-8IK1100 mobo (intel i875 chipset) with an 
Adaptec AHA-2940UW Pro PCI card, 3 SCSI drives, SDT-9000 DAT drive
Intel P4 2.60GHz with (and without) HT

2 gig DDR400 non-ecc dual channel (mobo manufacturer certified) samsung 
memory

Properly cooled case

No special kernel options
Redhat 7.3 with latest errata

Module                  Size  Used by    Not tainted
appletalk              28396  11  (autoclean)

scsi_mod              110876   3  [st aic7xxx sd_mod]

some oddities in dmesg; unexpected IO-APIC, detects some XEON? stuff


Symptoms:

The machine crashes after days or hours when using 2 gig memory.
When using 512Mb it runs fine for weeks.



I cannot come up with anything that triggers the crashes. Mem/disk/CPU 
load does not trigger it.

Tried both SMP and UP, (turned on and off HT in BIOS, booted SMP/UP kernel)

Replaced memory (different manufacturer, same specs)

Replaced motherboard (from ASUS->Gigabyte, roughly same specs)

Passes Memtest86



Anyone got any suggestions?
