Apparantly it does make sense.  I tried again in linux and it is working
perfectly now.  So this leaves two questions: (1) how does the state get
corrupted and (2) how can one get the state de-corrupted.

In my case (1) occurred (perhaps coincidentally) when I was connected with
the modem driver and bogged the computer down with the command
   dd if=/dev/zero of=swapfile bs=1024k count=500
to create a 500 megabyte file of zeros.  That made the whole system very
unresponsive (1-2 seconds between mouse updates, for instance) and by the
time it was done the modem was down and would come up again.  Kernel
messages from about that time:

And for me (2) eventually was accomplished in Windows XP apparantly by
disabling and re-enabling the modem driver.  A better solution would be
nice.


Hopefully this data point is useful to someone; at least for me I'm happy
now as its working again...  (Thanks, BTW, for the folks responsible for
writing and making available the driver!)
