wi(4) goes crazy, jumps off cliff

["James K. Lowden" <jklowden%schemamania.org@localhost>]

About once a week, my 3.1 kernel  wi(4) driver starts returning lots of
errors, then pretty soon locks up.  Sometimes I find it at the db> prompt,
but more often the only remedy is a power cycle.  The only change from the
GENERIC config is in the timer, because it's a Soekris box. 

Is this known, fixed, or new?  

The messages just before the dirge are attached below.  If you'd like me
to modify the kernel with more debugging messages, can do.  

Thanks for any help!
