After plugging in USB keyboard and loading uhci-hcd and

input: PS2++ Logitech Wheel Mouse on isa0060/serio1

(normally it's
input: ImPS/2 Generic Wheel Mouse on isa0060/serio1

and the mouse is moving very fast now. Previously
I either didn't able to make it work at all after such
freeze, or it worked automatically after loading usbhid.

BTW, it's 2.6.10, I can't made it work with 2.6.11 at all.

Can you try 'usb-handoff' on the kernel command line?

The problem has nothing to do with USB per se, as far as
I can see. PS2 keyboard and mouse does not work when
the USB subsystem (incl. usbcore) is not loaded. And the
problem is with PS2 keyboard/mouse, not with USB one which
works just fine.
Of course. Nevertheless 'usb-handoff' tells the BIOS not to meddle with
the PS/2 interfaces, too.

Oh me bad, I should listen to whatever is being said, instead
of doing my stupid guesses... Just rebooted into
with usb-handoff and both the keyboard and mouse are Just Works,
and psmouse driver loads almost immediately too.

Also, it works just fine after turning off USB Keyboard and
Mouse support in BIOS and without usb-handoff kernel parameter.

In 2.6.9 (it works just fine too, problem happens with 2.6.10
and up only), there's no such parameter in drivers/pci/quirks.c.

So is this a bios/mobo problem, or can it be solved in kernel

Thanks very much for your attention.
