Ok, so then at the moment - for those of us (like me where I have a 3.0GHz Prescott EM64T CPU), Knoppmyth used to run on R5-16 or some old rev just fine... Then after that, Knoppmyth would reboot on my machine on bootup and somehow disable around the core, so I just turned it off.
And I always used to see this in my dmesg:

yada yada...
I did look it up on the debian kernal sites and there was discussion of issues with the APIC reporting on "SMP" machines.. (shrug)
I've loaded up Windows JUST to check to make sure the CPU is working ok and it does (even with Intel's HT test program)
So... meh... maybe it's time to get a dual core.... and use this MB for
what it was meant... WinBlows.
Thoughts?
