6-BETA4 -> 6.0-RELEASE = sudden reboots

[Stepan Rakhimov]

I've just upgraded my home server from 6-BETA4 (that was stable and
worked without reboots for months) to 6.0-release. And now my server
suddenly reboots under any load, i'm even unable to rebuild my system to
 beta4 again. All the services are shuted down now (apache, mysql, smb,
nfs, ftp, ntp, ddclient) but problem still in place.

Any advise is welcome.
