Okay, folks. I have just upgraded my NeXT Cube to 68040. I'm running
NeXT Step 2.1. Since the upgrade (last thursday) the system has
crashed about 20 times. I saw the latest one. . . Here are the
contents of the last msgbuf. (This information didn't end up anywhere
on the disk. I thought savecore was supposed to try and save this
junk.)
unexpected kernel page fault failure
trap: type 0x410 fcode 5 rw 3 faultaddr 0xc0
trap: pc 0x406d3e4 sp 0x3fffe70 sr 0x2314
trap cpu 0 th 0x100473c4 proc 0x10046e20 pid 123
pcb 0x10e3a00c
traceback: fp 0x10e3ad10

panic: (Cpu 0) MMU invalid descriptor during table walk
I have also seen this:
panic: (Cpu 0) unwire: page not in pmap
Does it look like a memory problem to you or do I have a bad board
(mmu problem)? The system has original NeXT 1MB SIMMs in SIMM banks 0
and 1, 3rd party 1MB SIMMs in bank 2, and 3rd party 4MB SIMMs in bank
3.
Any suggestions?
