Hi Jeff,

I checked for any packages that could manipulate the CPU frequency. I

I changed the "maxcpus=4" in "grub.conf" to "maxcpus=1". Reboot.
Attempt to load "stock i8k" module. Crash. "/proc/cpuinfo" shows 1 CPU.
Care to try again with maxcpus=0? I seem to recall that this disables
even more of SMP than maxcpus=1 does.
Return system to previous configuration with "cpuspeed" and reboot.
My only other choice would be to physically pull CPU2, leaving CPU1 in
the system, but we know that config should work based on Harry's testing.
We don't, actually. You have different software environments and maybe
different BIOS options. And not exactly the same hardware either...
But I totally understand that you don't want to physically remove the
second CPU. I'm not even sure if that would help.
OTOH, if you see an option in the BIOS to disable HT, that would be
worth trying.
Slightly different crash with "maxcpus=0". See attached.
I will have to go the that office to change the BIOS in that machine for
retest. It could be a few days.
After a reboot with "maxcpus=0" in "/boot/grub/grub.conf", "cpuspeed" removed, and loading the "stock i8k" driver
