Default Bug#521135: BUG: unable to handle kernel NULL pointer dereference at 00000054

Package: linux-image-2.6.28-1-686
Version: 2.6.28-1
Severity: normal

Hello,

The rfcomm module induced a kernel BUG when booting. This is the first
time it happened, so I don't know precisely what triggered it on this
particular boot.
