It might be sata related, but I cannot tell for sure.
In summary, I have an Opteron 170 in a Shuttle SN25P (nforce4 chipset).
I've tested the ram overnight and swapped out every component in the
system except for the HDDs. I see these problems only with the
dual-core, and even on an older Asus nforce4 based motherboard.
I've had a hell of a time getting 2.6.18 to stay up longer then a day.
2.6.19 is better but I am still seeing strangeness. This morning I
noticed the following events (the complete dmesg is included below).
[36514.296462] Unable to handle kernel paging request at 00000000ff757c4f RIP:

[36514.515894] NMI Watchdog detected LOCKUP on CPU 0
..
[36519.958059] Unable to handle kernel NULL pointer dereference at 0000000000000038 RIP:
Now the system is quite non-responsive. I start programs, but they
don't run for a few minutes. Existing programs seem to work ok.
Any suggestions would be appreciated... I am going to boot with noapic
for now. From what I can tell things work better with APIC disabled.

Hmm. Something seems missing here. Chipset-specific driver not enabled?
I don't see any references to DMA mode or the controller type. It seems
like in this case something in drivers/ide is blowing up later on (which
shouldn't happen in any case but that code is not the greatest).
Myself, I would try disabling CONFIG_IDE entirely and enabling the
corresponding new libata PATA driver for this chipset's PATA ports (for
nForce4 it will be pata_amd). Even if it still doesn't work it may allow
the real problem to be diagnosed more easily.
