I switched from a T22 to a T23 last summer and have been
seeing occasional lockups which require popping the battery
and pulling the plug. Although this used to happen at
very long intervals on the T22 (seemingly X windows related),
it happens more often and with occasional dire consequences
on the T23.

As an example, last night I was watching a movie using
totem and had to pull the power and cold start about
4 times in the course of the movie. This is far more than
I would see in normal use.

Twice I have had the hard drive get so confused that
I could not boot off it. I believe I may have gotten
it to work again by taking it out of the machine and
waiting awhile for it to forget whatever strange state
it had gotten into during the lockup and ensuing=20
pulling out of the power cord.

A couple times I have also had the audio go into a=20
mode where it started 'screaming' and would not stop
until I rebooted.

This has happened over a number of kernels and in sarge
and now etch, although I think perhaps it got worse when
I did the upgrade to etch. Currently I have a 2.6.18=20
stock debian kernel.

The machine is far too old for this to be any of that
'Vista' intentionally pre-damaged hardware crap, so I=20
wonder if this is yet another power management issue.

Has any one else had similar problems? Any ideas on how
to prevent it?
