Hi,

Just for the record as I won't provide much information (I get no core,
and backtrace should have been appended to msgbuf, but it wasn't ...).

I just had a panic in sbdrop() with a -current kernel from yesterday
while trying to kill (with ^C, from console) wpa_supplicant(8). The
network (wifi only) did only timeout, no problem accessing the machine
through ssh before the panic.

By looking at the code, it seems that the `len' argument get out-of-sync
with the total length of mbuf waiting in the sockbuf.

I also had a panic yesterday with 4.0beta kernel, but I didn't have
time to see where it came from.
