This can be caused by a flaky connection or a low-power condition on

If not, reboot and connect things one-at-a-time to see what triggers it.
This doesn't mean much to me, but it may give some clues to someone else:

Taken from logwatch. The hdc errors are when I have a dvd recorded with a
weak signal. They often will play on my standalone recorder, but not on this
box. I ignore them, but the sdx errors are more likely to be connected with
the runaway problem.

I wonder if you are having a power supply problem looking at the errors.
If you have sensors running, check your voltages. Or check them in
your bios if you can.
are the sd(x) errors external devices or internal drives?
I had a power supply that was just at the limit and it affected DVD
usage. Then I had a power supply that had a low 5volt rail that was
causing hard drive errors.
The low power supply could be affected when you plug in a USB device.
FWIW, my low voltage rail was on a power supply that was less than a
year old.
