Description: Kernel panics when inserting a snapstream firefly RF receiver. If cold plugged, the kernel panics when udev is processing events.

Additional info:
* package version(s):

* Linux radiant 2.6.30-ARCH #1 SMP PREEMPT Fri Jun 19 21:25:17 UTC 2009 i686 AMD Athlon(tm) XP 3200+ AuthenticAMD GNU/Linux
* core/udev 141-3

* Device info:

* ID 0bc7:0008 X10 Wireless Technology, Inc. Wireless Transceiver (ACPI-compliant)
* lirc_atiusb driver

* config and/or log files etc.

* kernel.log shows nothing at the time of the crash.

Steps to reproduce:

insert device after boot

or

insert device, boot, wait for udev to start processing events.

* Additional notes

* This device is known to work on another machine running archlinux. The working machine is running a 2.6.29-ARCH kernel.
* I used a PCI usb controller as a control between both machines. The controller and receiver work on the machine with the .29 kernel, but the same pci controller and rf receiver don't work in the machine with the .30 kernel.
