random system freeze

[eric-yrHdaQSNc4gdnm+yROfE0A at public.gmane.org (eric c)]

hi all.  i'm experiencing seemingly random system lockups.  i get no 
response from the keyboard or mouse.  <cntl><alt><backspace> OR <delete> 
do nothing.  <Alt><SysRq><just about everything on the keyboard here 
including smashing my forehead on it> also do nothing.  i end up doing a 
hard reset.  i have a "mp-bios bug 8254 timer not connected" upon boot 
but this may not be important.  see previous thread 
http://lists.blu.org/pipermail/discuss/2007-May/053776.html

i had the problem with fc6 (gnome) and now have it with f7 (kde).  it 
seems to be more frequent with f7.  i was hoping the upgrade would solve 
the issue.

what log files should i be digging in to find the key to my problem? 
thanks for any suggestions.  - eric c.
