>Description:
FreeBSD 5.4 and 6.0 freeze in 2-processor configuration on SuperMicro P6DLF motherboard after about 2 days of work. The computer works perfectly under 4.*. The following influences the frequency of the bug: Setting HZ=100 makes it reasonably rare; underclocking to 50 or 60 MHz causes freeze after some minutes of work. Removal of second processor removes the problem.
When the freeze occurs, there is no reaction to anything except RESET - no CTRL/ALT/DEL, no CTRL/ALT/F1, no CTRL/ALT/F1, no CTRL/ALT/ESC (kdb compiled in),
no NMI button, no mouse movement. When the fault happened during DIVX4 playing,
the SBLIVE continued to reproduce the last scream. The processors are warmer than in idle state.
The following doesn't influence: Removing from kernel anything not needed, adding MPT_WATCHDOG, moving HDD to Promise or PIIX4, changing 3DFX Banshee to
S3 Savage 4, changing UDMA to PIO, adequate cooling and powering, replacement of
processors, memory, HDD. Not tested: SCSI HDD, M/B replacement, use of a pair of
P-II instead of Celerons, removal of CD-RW,fxp or SBLIVE, enabling APM or ACPI. M/B is powered from AT p/s.

===============================================================================
>How-To-Repeat:
M/B SuperMicro P6DLF + 2 Celerons/500 + 2 Socket/slot adapters + RAM etc. Set clock to 60 MHz, boot SMP kernel and wait. Maybe other 440LX m/b, too
>Fix:
Remove second CPU to fix fully. Or set HZ=100 to make system at least more usable than Windows-95
