NetBSD 7.0 RC1 radeon crashes (in intr_biglock_wrapper() ?)

[Silas Silva <silasdb%gmail.com@localhost>]

Hi there!

After having X running with radeon (no heavy usage), network stopped.
^C couldn't kill jobs and after a while X just froze.  After changing to
a text mode console ddb just sync'ed to get a coredump.  uname,
backtraces with gdb and output of "dmesg -M" are just below.  Please,
tell me if you need more information.

(Computer is a Lenovo X100e netbook).
