Attached is one Netcomm USB modem which uses the ucom / uftdi drivers, and is configured for auto answer. Source is 6.0 stable as of today 7th Dec 2005. Devices in /dev that get created are: cuaU0 cuaU0.init cuaU0.lock ttyU0.init ttyU0.lock ttyd0 I have added the following to /etc/ttys: ttyU0 "/usr/libexec/getty modem.230400" dialup on insecure and this to /etc/gettytab: modem.230400|modems-230k:\ :hw:np:sp#230400: As soon at the modem rings, the machine panics. I don't think the modem even gets time to pick up the line. This doesn't happen on a 5.4-stable box with 6 modems connected, but 5.4-stable appears to have other "hanging" issues, thus why I am trying out 6.0-stable. Recent changes to ohci.c (1.154.2.1) in this area (2 days ago) ?? Should I raise a PR ?
