Subject: USB doesn't work with 440MX chipset, PCI IRQ problem?

Hi all,

I got a new laptop with an Intel 440MX chipset, and USB doesn't work at
all. I tried both the UHCI drivers, but none of them works. The drivers
load OK, the USB hardware is detected, but as soon as I plug in a USB
device, I get the following debug messages (this is with a Logitech USB
mouse):

  hub.c: port 1 connection change
  hub.c: port 1, portstatus 301, change 1, 1.5 Mb/s
  hub.c: port 1, portstatus 303, change 0, 1.5 Mb/s
  hub.c: USB new device connect on bus1/1, assigned device number 19
  usb_control/bulk_msg: timeout
  usb.c: USB device not accepting new address=19 (error=-110)
  hub.c: port 1, portstatus 303, change 0, 1.5 Mb/s
  hub.c: USB new device connect on bus1/1, assigned device number 20
  usb_control/bulk_msg: timeout
  usb.c: USB device not accepting new address=20 (error=-110)

I think the timeouts have something to do with interrupts not coming
through because the interrupt counter for the USB port is not
increasing:

Some information about the laptop: Asus P8300, Celeron 500, 128MB,
Intel 440MX chipset, running SuSE 7.0 and linux-2.4.0-test12-pre3.
