Except for bugs in glibc that trigger things happening as root which go
on to do stuff like power down the system (root is allowed to power
down/reboot/etc). That is a fairly unlikely case.

The first thing is to find out which glibc version is the latest that
works, which is the earliest that fails. Second is to try and find out
what apps or event is the trigger for the fail (eg can you boot into text
mode with init s and then run 2 or 3 cpu hogs all day)
