Dear BUMers,

Our SGI O2 began to crash once in 1-2 weeks leaving a following message in
"analyze" file:

Jan 9 13:11:17 2E:ntc2 savecore: pb 50: <0>PANIC: TLBMISS: KERNEL FAULT
Jan 9 13:11:17 2E:ntc2 savecore: pb 51: PC: 0x8010e8f8 ep: 0x8031fe70
Jan 9 13:11:17 2E:ntc2 savecore: pb 52: EXC code:8, `Read TLB Miss '
Jan 9 13:11:17 2E:ntc2 savecore: pb 53: Bad addr: 0xff800000,cause:
0x8<CE=6145
Jan 9 13:11:17 2E:ntc2 savecore: pb 54: <6>

IRIX version is 6.5.11.

Did anybody experience a similar problem?
Is it a hardware or software (IRIX krernel) problem?
And how to fix it?

Thanks for any suggestion.
