but I checked for a bios update first. And sure enough like they read my mind, just posted online today, an update. Here are the details of fixes:
" Checksum: 8B00H Date Code: 12/05/03
1.Support 0.18 micron AMD Duron (Palomino) CPU.
2.Add C1 disconnect item."..........Jesse
-Bob said that about his bios update fixingA bios update for MSI K7N2 MCP2-T nforce2 board
fixed the crashing BEFORE these patches were developed,
but there was no documentation that would relate or explain.
Disconnect was ON!!!Last night, I updated the bios to the 12-5-03 released yesterday (see above). I looked at the new option under Advanced Chipset Features, "C1 Disconnect". It has three selections: Auto, Enabled, Disabled. There seems to be no default. The item help says:
"Force En/Disabled or Auto mode:
C17 IGP/SPP NB A03
C18D SPP NM A01 (C01)
enabled C1 disconnect
otherwise disabled it"
Auto sounded nice, so I selected that first. I compiled a new kernel without the disconnect off patch, or the ack delay. These are the exact patches I used on 2.6.0-test11:
patch-2.6.0-test11-bk8.bz2
acpi-2.6.0t11.patch acpi bugfixes from Maciej.
nforce-ioapic-timer-2.6t11.patch from Ross Dickson. Timer patch.
forcedeth.patch Patch stolen from -test10-mm1? Unused.
forcedeth-update-2.patch Same.
Sure enough, under this kernel, no lockups. Athcool reported Disconnect was "on".
<snip> ...one case the bios update fixed the problem
The thing that strikes me funny is that you get no crashes with the...and at least two motherboard makers have voodoo
updated BIOS and Disconnect on, but without the updated BIOS we have
to turn disconnect off with athcool or the patch? This makes me think
that there is some voodoo going on in the BIOS update that they aren't
saying, surprise surprise, or something is just slowing down the time
it takes for it to crash. I say this because I have gone 5+ days
without any of the patches from these threads, acpi apic lapic
enabled, and CPU disconnect on as stated by athcool. This was with
much stress testing, idle time, etc. One day I just ran a grep that I
have done probably 30 times and boom, hang.
Good luck, hope the BIOS is the trick, now off to see how I can get
ASUS to put the C1 Disconnect in the next revision.
