For what it's worth, I see vaguely similar behavior on my IBM x3100M4 
workstation.  In my case, there are a handful of USB devices that, for 
whatever reason, cause the server to freeze and/or reboot immediately 
after the GRUB menu disappears.  When I need to reboot the machine, I 
have to remember to disconnect those devices (which means rebooting 
remotely is impossible).

USB wired keyboard and mouse:  boots fine.

USB RS-232 serial converter (Prolific):  boots fine.

USB wireless keyboard/mouse receiver (Logitech): reboot after the GRUB menu

USB wireless mouse receiver (MosArt): boots fine

USB audio DAC (Behringer): reboot after the GRUB menu

USB webcam (Logitech BRIO): hangs with a blinking cursor after the GRUB menu
