I've got a 164LX. I've been getting "processor correctable error"
messages in the past few days. Now mozilla seems to be able to
crash my box multiple times a day. Big bummer.
From the crash that happened just a few minutes ago I got this:
97 496 495 494 493 492 491 490 489 488 487 486 485 484 483 482 481 480 479 478 4
77 476 475 474 473 472 471 470 469 468 467 466 465 464 463 462 461 460 459
unexpected machine check:
mces = 0x1
vector = 0x660
param = 0xfffffc0000006068
pc = 0xfffffc00004fc8c8
ra = 0xfffffc0000309abc
code = 0x203
curproc = 0xfffffc0005124e68
pid = 467, comm = mozilla-bin
panic: machine check
dumping to dev 8,9 offset 4191
dump device not ready
Now, I know why the dump device isn't ready: It was dumping because
of a machine check. When it got a check in the middle of the dump it
I think the first crash had a vector of 0x670. I didn't write down
the whole message because I thought I could get it from the dmesg.
Oops, overflowed the buffer. Is there a ddb command to reboot without
a dump? I'll have to check.
Anyway, what do these machine checks mean? Is this a bad CPU? Bad board?
Bad memory? I've got a gig of memory, should I yank half of it?
Are there any public docs so I can just look this up myself?
Anyway, thanks for any help.
