Anything. It depends on how linux rebooted the machine, and it's never a
cold boot just like on power on.

I asked you on another message to try rebooting from another OS. Did
you? I got it wrong then - I understood you do not have the problem with
FC4. Suggestions for other OSes (assuming you do not have them
installed): Knoppix as well as some other live CDs or rescue floppies, a
live XP CD created by BartPE, a FreeDOS floppy, a FreeBSD live cd (I
never tried any but google shows there are a few, and for rebooting I
guess any should be good enough).

You might also try rebooting from inside grub. Press 'c', then 'reboot'.
