7.2-stable #3 seems significantly less stable.

[Steve Franks]

I have no hard metrics, but having gone from 7.2-release to 7.2-stable
sometime in the last couple weeks has really made my usb experience
quite unpleasant.  I now have much trouble with loss of communication
to uslcom devices when closing and reopening them (*not* plugging and
unplugging them).  Simply closing and reopening the port causes the
open to freeze about 25% of the time.  I seem to have similar problems
with umass devices.  I tend to leave evertthing plugged into the same
hub and when it freezes, I unplug the cable from the hub.  That caused
a freeze & reboot (I assume there was a panic, although no output on
the screen).

Anyway, like I said, no real chance of debug with it being so
intermittent, just an FYI.  Just thought I'd issue a report in case we
just merged head into stable and most people think it's great - I'm
not finding it great at the moment.  If I do find a repeatable
sequence of events, I'll send some info.

Best!
Steve
