System: NetBSD 1.5.2 NetBSD 1.5.2 (ALTAIR) #2: Fri Dec 7 01:42:35 CET 2001 i386

	I've got an ECS K7S5A mainboard which uses the SiS 735 chipset.
	Every time the X server is resetted, for example with
	Ctrl+Alt+Backspace, the user has to press a key, otherwise the
	system will hang for a long time (probably infinitely).
	The kernel prints the following:

	ohci0: scheduling overrun
	ohci1: scheduling overrun

	I understand that that's got something to do with USB; I don't
	have any USB devices connected, however.

	See above.
	Hit a key when the system appears to hang.
