I don't think that's a rootkit.

Sounds like a nasty lockup to me.

Have you updated your system since initial install?  My experience with 
lockups usually involves upgrading the kernel; either things go screwey 
after a kernel update (not common), or things are haywire until an 
update.

You could also have a hardware issue too.  Memory can be checked with 
"memtest86".  Motherboards?  Dunno.  Could be a bios update is needed.

Oh, and let's change the topic a bit...
