Endless print of uhci_result_common: failed with status 440000

[Zdenek Kabelac]

Hi

While debugging resume problem with Intel HW I've been hitting problem
with endless print of  usb 1.1 error message on my T61.
(See my other similar post
http://marc.info/?l=linux-kernel&m=130221292724436&w=2)

This time the problem is generated by Bluetooth device.

Often just only several messages are printed - and then machine
suspend - so the log usually contains only several such message - if
at all - however today with debugging and serial console logging -
I've seen several times - that suspend resulted in endless unbreakable
loop.

As a workaround - one could just disable BT device:
"echo disable >/proc/acpi/ibm/bluetooth"

Here is the log:

Googling it - seems it's common issue of this BT chipset - but I think
is should not cause suspend deadlock ??
