I have seen this happen occaisionally to very often with several 
versions of the kernel above 2.4.18.  A different build of the same 
kernel tree may behave better or worse than another build.  It appears 
to me to be a race condition on the open of the USB tty device but quite 
whats causing it I don't know.  I do not know of any kernel patch that 
actually fixes it.... the last kernel set I used (2.4.21-rc8 + ac) never 
showed the problem in the few weeks I used it, the current (2.4.21 
laptop build - see sourceforge) has shown it one in 50 hotsyncs (rough 
estimate).  Another kernel (on different hardware to that I now use) 
would hit one sync in 2.

We need to get Greg K-H interested in this one, I think.
