Thanks.  I'm not having that problem, but I'll add that patch locally to
make sure it doesn't break anything on my config.

So far for me, Ubuntu has been working flawlessly.

OSX is a little flaky.  It works, but as long at the card isn't
unplugged for more than 2-1/2 minutes.  That's better than before.  I
think the original patch uncovered another problem,  I don't think it
introduced an error.  But anyway I'll try to get that issue resolved here.
