freebsd 6.0 system freeze: kernel(smp) problem?

[nkiuuu]

Hey Guys

I've got a problem with my freebsd 6.0 maschine on a sun v40.

Sometimes (don't know, when and why) the system completly freezes and i have to reboot it.

the following lines are from the console log:

mpt0: Request 0xffffffff808592e0 Timed out.
mpt0: Request 0xffffffff8085b3c8 Timed out.
mpt0: Timedout requests already complete. Interrupts may not be functioning
mpt0: Request 0xffffffff8085ad08 Timed out.
bge0: watchdog timeout -- resetting
bge1: watchdog timeout -- resetting

further i got a kernel with smp enabled, could that be the problem?
would an upgrade from freebsd 6.0 to 6.3 help anything?

Thanks,
nkiuuu

May not be related, but I have had onboard Broadcom gigabit ethernet (bge) lock up my system randomly. Try disabling the Broadcom ethernet physically with jumpers (disabling in BIOS isn't sufficient) and use a non-Broadcom network card. That cured my problems.

are you using a Sun Fire V40 too?

before we enabled smp (2way-maschine) we never had problems like this.

i got this on the freebsd mailinglist but it seems that nobody found any reason.

Could a system upgrade solve this problem(s)?

Cheers

An upgrade certainly won't hurt... give it a shot. I believe 6.0 is no longer supported.
