Here's a REPORTING-BUGS format problem report for my cdc_acm woes.
PROBLEM: Kernel OOPS when cdc_acm modem is unplugged during a ppp session.
I have a cdc_acm compatible modem. It is a Motorola v66 phone with a
USB tether, for GPRS 'net. Unfortunately the kernel OOPSes if I unplug
the modem during a PPP session.
Re-plugging the modem tends to make a ttyACM1 available. Unfortunately
ppp is ornery about using ttyACM1 after a ttyACM0 failure.
The bug has reproduced itself equally on all tested kernels between 2.6.10
and .12.1 including the vanilla kernel.
Plug modem, dial ppp, unplug --> OOPS.
If ppp is stopped before unplugging the modem then linux does not OOPS.
