I have also problems with USB on recent current (previous was few weeks
old).

It panics on each boot:

==================================================================


I have found way how to workaround panic.
If I turn on USB dongle while boot (after usb bus detected) it boots ok.
But If I boot with turned off USB dongle - it panics, same If I boot
with turned on USB dongle. (also it is same with usb mice or keyboard).

I have allways turned on umass on-board card reader.

There is my usual list of USB devides:

# usbdevs -v
Controller /dev/usb0:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00
 port 1 powered
 port 2 powered
Controller /dev/usb1:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00
 port 1 powered
 port 2 powered
Controller /dev/usb2:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00
 port 1 powered
 port 2 addr 2: full speed, power 100 mA, config 1, UGX(0x3003), ALPS(0x044e), rev 7.81
Controller /dev/usb3:
addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), Intel(0x0000), rev 1.00
 port 1 powered
 port 2 powered
 port 3 powered
 port 4 powered
 port 5 addr 2: high speed, self powered, config 1, USB Memory Stick Slot(0x014d), Sony(0x054c), rev 1.10
 port 6 powered

Last "good" kernel dated Dec 9 2004. (or near this date).

As I notice it allways panics when some process gets Giant, (usually it
is bluetooth process)

Looks like it is USB problem, but probably it is bluetooth related. I am
not sure.

I can provide more details.
