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...
