server madness

From: mowgli

have you guys ever heard of this/have any clue how to explain it:

i have 5 servers all hooked up to 1 linksys 8 port kvm via vga/usb cable for each.  the cable has vga & 1 usb (which is for the mouse & kb connected via usb to the kvm).  well 1 fine day, 1 of the servers crapped out; i thought it was the drive(s) but they tested fine.  so perhaps its the mobo or raid card or sas/sata host card (i got weird I/O errors before it crapped out).

but here's the odd bit:  when the funky server gets to the grub menu (reinstalled ubuntu), no matter what i push (enter, p, esc) it immediately reboots the server.  BUT MORE!  that also reboots all of the other servers sometimes.  just randomly sometimes.

have you ever heard of this?  1 server rebooting all the servers on a kvm!  randomly!  i cant even figure out why the bad server reboots when i press any key at the grub menu.  is the usb port failing?  what can i test (ran all the bios hw tests & all passed).  & how do you explain it randomly rebooting all the servers?!
