That's nice, yes.  The wpi(4) driver seems to support the chipset of
your wlan adapter :)

Hmmm, that's a bit bad.  Is `Fn+F2' the key that turns wireless OFF/ON
for this laptop?  Maybe the driver is crashing because the device
detaches and re-attaches while the driver is stuck somewhere :(

If you think you can grab a kernel dump from this, maybe it's going to
be useful to debug the problem.

I don't see `BCM5756' or `5756' anywhere in the manpages or the source
of the kernel in of 8.0-CURRENT either.  I think this is not supported :(

Heh, nice.  I see you are running an amd64 build of FreeBSD, and there
are *lots* of memory on this laptop :)

One of the tests you can run, to find out what is broken in wpi(4), is
to build a kernel with DDB/KDB support, and grab a kernel dump when the
wpi(4) interface stops working.

The ``Developer's Handbook'' can help you build a debugging kernel:

  
http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html

Using DDB to trace through the `live' kernel while it is stuck is a bit
tricky, but if you manage to grab some of the DDB output (i.e. with a
serial console or even just a photograph with a camera), then we can
mail the developers of wpi(4) and ask them for more help :)
