Subjectbaycom_ser_hdx Oops 2 crash

Hi Tom, I ran the following script, then TNOS, and had a problem!

# file: /root/baycom/start - load and set Baycom driver
setserial /dev/ttyS2 uart none
modprobe baycom_ser_hdx mode="ser12*" iobase=0x3e8 irq=3
ifconfig bcsh0 hw ax25 VE3HUR-1 up
net2kiss -i bcsh0 -v /dev/ptypf &

I then ran Tnos and got:

I had to copy this off the screen, so I hope its correct and of some use.
I've tried to reproduce it exactly as it appeared.

The configuration was: - 2 Pentium smp
- Linux 2.2.13 (kernel and modules custom compiled)
- Slackware 7 distribution
- ax25-tools-0.0.5 from the Slackware
"contrib/ham/ax25" directory
- Tnos 2.10/ELF

In an attempt to simulate the operation of the old baycom character device,
I was using the above script, set up for baycom_ser_fdx, and replaced the
bc0 device in the Tnos configuration with ttypf. This didn't work well
(stopped transmitting after a short, but random interval) so I decided
to test using baycom_ser_hdx (for the first time and last time).
