-- I don't think this issue has anything to do with motherboard
maker or BIOS rev. Most of the people with this problem are
not overclocking and have stable machines with other OSes or
under certain conditions namely:

* In general NForce2 boards are stable under windows 2000
- a far as I can tell

* The boards are stable under certain conditions. The final
test for this (Proposed by Allen Martin
[AMartin at nvidia ! com] is to get a stable well supported
PCI-IDE add in card and ignore the "AMD/NVIDIA" IDE onboard.
(First pointed out by Ian Kumlien I believe)
"If we all have that, and deadlock when using the amd/nvidia
driver.. then we know that that might be the fault. The
machine still locks for a while so, it's not just the ide,
but it might be a good place to start."

* NForce2 boards are stable when using APIC and using generic
IDE driver. This is painfully slow but is stable.

-- In general: I dont think it should be so easy to blame
the BIOS. If one isnt overclocking and using the SPD on the
memory and using conservative settings, what difference
should that make? And if the board is stable with another
OS I take this "BIOS blaming" and basically throw it out. BIOS
is a deprecated arcane ridiculous thing and should never be
trusted. I have seen on several nicer dual SCSI based
machines messages on boot about certain values being changed
or fixed up.

-- Fixing this for 2.4.x too is important so be sure to try
and find out if 2.4.23 hangs if you get a stable 2.6 thing

Thanks everyone for your continued interest in this, I'll
try and test the no-onboard-PATA + UP LAPIC and IOAPIC and
add-in-card-PATA with no onboard PATA + + UP LAPIC and IOAPIC
when I get a spare moment which is rare.
