My setup is:
ASUS Pundant Booksize PC Celeron 2.66Ghz, 512M ram, 4 USB ports.
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 ?
Paul.
