Hi,

I am not sure if this is the proper list for this.  Please mail me
privately if I should take this elsewhere.

I am having problems with the umodem driver with a Ricochet GS USB modem
under stable (built June 3).  The modem is new so I don't know if this
is a new problem.  When the modem disconnects (ISP disconnects me or I
go out of range) FreeBSD crashes with this output...

-------------------

Can anyone tell me where to go from here?  The kernel is basically
GENERIC + umodem - NIC support.  Please CC my on any replies as I am a
digester.

Thanks,
-Mike
