Did you do the usual -- vacuuming out the dust, re-seating RAM and
controller cards, cables, etc.?

Some device on the PCI bus is complaining, etc. Be nice if just a
little physical housecleaning gets rid of those. Otherwise, well, ...
BTW, you can search the web on the device address in that part of the
message, too, to try to figure out what device is complaining. But all
the zeros make me think it's the bus controller itself. (Not that I
know anything about this kind of stuff.)

eek. Seem to have trouble getting stuff into or out of swap.

And you could disassemble that and likely be none-the-wiser, although,
again, you might find physical port addresses and such. Which may or
may not help.

And the journal process is not stable. Likely to lead to silent data
loss until it gets bad enough to start casing panics and such.
