[mythtv-users] System Lock Up?

[apt22 at drexel.edu]

Hi-
My system has been getting all locked up and basically freezing allowing 
me to do absolutely nothing except hit the hard power switch.  At first 
I thought it was a Myth issue, but after trying different things, I am 
not sure what is causing the problem.  Here are my machine specs and 
details of this issue, any help would be greatly appreciated:
    Athlon XP 2700/512MB/GeForce4 MX/Hauppauge 250
    Gentoo 2.4.22-r5/IVTV 0.1.9
Once upon a time I was running Myth 0.12, basically no problems, I 
bought a new HD and decided I would benefit from LVM, so I nuked 
everything.  Re-installed everything, this time Myth 0.13 b/c it was 
released and I thought I'd upgrade to keep current.  Myth 0.13 was 
giving me all sorts of problems after scouring the net and forums, I 
found a poster with similar problems and Isaac replied telling him to 
upgrade to Myth CVS to fix them.  I followed this advise, installed CVS 
and just as Isaac said, everything was working.  After 1-2 days running, 
my machine started freezing up, nothing actually crashes, just freezes 
and doesn't respond to anything(keystrokes, SSH terminal, etc).  Logs 
report nothing interesting.  One thing I've noticed is that the CAPS 
LOCK and SCROLL LOCK lights on my keyboard flash repeatedly forever 
until I power the box down.  So, I figured it was probably a CVS bug or 
something, I uninstalled all Myth components(including nuking database) 
and switched back to Myth 0.12(which previously I had no problems 
with).  After running this version for a day and a half, the same thing 
started to occur.

So, basically, my question is whether anyone else has seen this kind of 
thing and if anyone had a guess at what was causing this and how I might 
go about further trouble-shooting/fixing?

Thanks in advance,
Drew
