In case there is a fix that you were trying in 2.1.94, I
I must report that this problem persists in 2.1.94. I can also
confirm that the problem occurs within about five minutes of
booting even if I do not start X windows. I hope this
data point is helpful.

I have attached the output of lspci below, in case other
people experience the same problem and want to check for common
hardware. This machine is a Pentium II-300 on an Intel motherboard
with a 440LX chipset and some kind of built-in sound.
