I posted last week in regards to a Tyan Tiger 100 S1832DL motherobard
that was strangely running processors uncontrollably
(http://marc.theaimsgroup.com/?l=linux-smp&m=96018117825734&w=2). I
have since done further research with swapping out hardware finding the
best available hardware combinations to rule out IRQ mishandling. I
have tried various BIOS revisions, some with more success than others.
All of the results have been the same in varying degrees with both MPS
1.1 and 1.4 and all the latest kernels. Under the better BIOS
revisions, xmms will start out racing both CPUs at 50% and then after a
while drop off to about 2% on each CPU. This is an improvement over
some of my other results, but intensive things like Quake still run both
processors at 100% (when only one should be running) and hang the
machine.
I have included an updated dmesg output, and I noticed under all BIOS
revisions that the product is being identified as a 440GX board. This
is definitely incorrect, and is a 440BX, as identified by the spec pages
and by the BIOS on each boot. Would this mess up things in a drastic
manner, and is there any way to force the correct ID? I've tried to
rule out all the possibilities I can on this, and I really don't think
my hardware or kernel configuration are the issue. Perhaps somewhere
between the BIOS revisions and SMP initilization I'm missing something?
I'm out of ideas on this, besides the 440GX identification, and this is
really starting to suck bad. =)
