There may be updates to the driver soon; perhaps they will
help this.

The firmware is reloaded each time the chip is started, and
the chip is
stopped (and I think/hope mostly powered off) when
ifconfig'd down.
Unfortunately, the firmware loader has an annoying
requirement to
allocate memory in a contiguous chunk, and that can fail
after some
running time. One way to work around this is to free up or
page out
enough memory that there's a suitable chunk free. Quitting
a big app,
or something like:
dd if=/dev/zero of=/dev/null bs=512m count=2
usually does the trick. adjust bs according to the amount
of physical
ram in the machine (ie don't make it larger so you're paging
dd
itself).
Hopefully the underlying issue will be fixed with a smarter
loader.
