[Casandro <casandro_lion@xxxxxx>]

The exact same crash also happens when I manually unload the module with
rmmod.

I suspect there to be an error in the function usb_remote_disconnect,
but I'm not really familliar with the syntax of pointers in C.

package lirc 0.8.6-0ubuntu2 kernel oops on removal

Status in “lirc” package in Ubuntu: New

Bug description:
Binary package hint: lirc

lirc causes a kernel oops upon rmmod. This causes each upgrade of lirc to fail until the next reboot. It worked fine with the lirc version in jaunty, but broke with the next newer lirc version, and has been broken since a while. apport-kde also crashed trying to create a proper report, so no attachments today.
