Hi gang,
I have a small but recuring, and annoying problem. Every now and then,
my little xconsole starts spewing out the messages below, after which X,
and sometimes the whole system, usually crashes. It's somewhat
disconcerting.

My guess is that there is a problem somewhere with the swap device, and
when trying to access this, somethings going wrong, resulting in memory
corruption and a crash. That is only a guess so far, but it's the best I
can come up with.
What I would like some clues on is, is this the likely problem, and if
so, what can I do to fix it.
As I'm writing this, I decided to include the output of the partition
table on this disk to help diagnose the problem. To me, it doesn't look
especially healthy!
Disk /dev/sda1: 255 heads, 63 sectors, 527 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System
/dev/sda1p1 ? 115306 236915 976827065+ 6c Unknown
Partition 1 has different physical/logical beginnings (non-Linux?):
phys=(80, 10, 0) logical=(115305, 135, 4)
Partition 1 has different physical/logical endings:
phys=(371, 101, 33) logical=(236914, 223, 5)
Partition 1 does not end on cylinder boundary:
phys=(371, 101, 33) should be (371, 254, 63)
/dev/sda1p2 ? 120529 208571 707199029+ 74 Unknown
Partition 2 has different physical/logical beginnings (non-Linux?):
phys=(367, 97, 46) logical=(120528, 70, 23)
Partition 2 has different physical/logical endings:
phys=(370, 104, 37) logical=(208570, 123, 12)
Partition 2 does not end on cylinder boundary:
phys=(370, 104, 37) should be (370, 254, 63)
/dev/sda1p3 ? 1 1 0 20 Unknown
Partition 3 has different physical/logical beginnings (non-Linux?):
phys=(288, 68, 18) logical=(0, 0, 33)
Partition 3 has different physical/logical endings:
phys=(32, 32, 32) logical=(0, 0, 32)
Partition 3 does not end on cylinder boundary:
phys=(32, 32, 32) should be (32, 254, 63)
This disk is a 4.something G SCSI Quantum Fireball. I haven't
experienced any problems with it until recently. The only thing that
seems to be showing problems is the swap (I have lots of data on this
drive, and haven't lost anything recently).
Anyone have any ideas?
cheers.
