Public bug reported:

Binary package hint: linux-source-2.6.15

Attaching my Nebula Digitv USB DVB-t device causes my usb subsystem to crash. After some googling I think the issue is related to this thread:
http://linuxtv.org/pipermail/linux-dvb/2005-December/006911.html

Linux apollo 2.6.15-23-686 #1 SMP PREEMPT Thu May 18 17:31:41 UTC 2006
