Architecture: i386
Machine: i386
        Semi-reguarly, an i386 MP machine (dual Xeon, 2G RAM, around
        June 2003 vintage) freezes for about 15 seconds.  I see the
        following messages when this happens:

		pms0: resetting mouse interface
		pckbport: command timeout
		pms_disable: command error

        This appears to be MP related.  I can't reproduce this with a UP
        kernel (GENERIC, GENERIC.NOACPI, GENERIC with MPBIOS/ioapic),
        and happens with all MP kernels I've tried (GENERIC.MP,
        GENERIC.MP with ACPI disabled, GENERIC + PCI_INTR_FIXUP).

        I also occasionally see a momentary freeze (less than a second
        or so) and just see the:

		pms0: resetting mouse interface

        message, without the following "command timeout" or "command
        error" messages.

        Relevent attach messages for mouse and keyboard are:

		pckbc1 at acpi0 (PNP0303): kbd port
		pckbc1: io 0x60,0x64 irq 1
		pckbc2 at acpi0 (PNP0F13): aux port
		pckbc2: irq 12
		pckbd0 at pckbc1 (kbd slot)
		pckbc1: using irq 1 for kbd slot
		wskbd0 at pckbd0: console keyboard
		pms0 at pckbc1 (aux slot)
		pckbc1: using irq 12 for aux slot
		wsmouse0 at pms0 mux 0

	Full dmesg is available for various kernels.

        The mouse is a M$ IntelliMouse Explorer.

        Not sure..  The problem appears to happen when the mouse
        moves, and seems to happen every hour or so, sometimes longer,
        sometimes only minutes apart.

        None given.  Or use a UP kernel :/ I'm about to try a USB mouse
        instead of a PS2 mouse (well, same mouse, different plug).
