Re: Panic caused by bad memory?



I can't get a kernel dump since it fails like this each time:

dumping to dev #da/0x20001, offset 2097152
dump 1024 1023 1022 1021 Aborting dump due to I/O error.
status == 0xb, scsi status == 0x0
failed, reason: i/o error

Bad memory seems unlikely to cause an I/O error trying to write the
dump to the swap partition. I'd guess a dicey drive -- and bad
swap space could also account for the original crash. You might
be able to get a backup by booting single user, provided nothing
activates the (presumably bad) swap partition.
