Hi,
It seems the baycom driver (for ham radio) needs some attention.
The problems:
- the baycom_ser_hdx driver does not work at all: very occasionally it
switches the radio to send and transmit the data, but that's only one
in thousand
- the baycom_ser_fdx does seem to send, but only 1 or 2 packets, then
something odd happens: the radio does transmit something but it is not
recognizable as data. it sounds like a couple of ticks, not the
recognizable modem sound. Important: if I do a sethdlc command, it
again does send 1 or 2 valid packets!
The system on which I try it, is a 3.2GHz p4 (with HT) so I don't think
it is a problem with the system not keeping up.
The pc is a:
Manufacturer: IBM
Product Name: 8215F7G
Version: ThinkCentre M52
Things are setup like this:
/bin/setserial /dev/ttyS0 uart none
/sbin/modprobe baycom_ser_fdx 'mode=ser12*' iobase=0x3f8 irq=4
/usr/bin/sethdlc -i bcsf0 -a txd 200 slot 100 ppersist 40 half
/sbin/ifconfig bcsf0 hw ax25 FH1GOU-1 up
I played a little with the txd and does not help. Using full or half
does not make a difference so far that it looks as if the first part of
the packet is missing if I full duplex mode but I'm not entirely sure of
that (no second modem setup).
I verified the problem by listening with a second radio.

I'm trying to bisect this problem.
The problem now is, that the 3.1.0-rc9 crashes just after it loads the
initramfs. Well, it says it is doing that and then all fans speed-up and
the system locks up.
What to do now?

This 3.1.0-rc9+ is, by the way, a kernel build on a different amd64
system using fakeroot make dep-pkg
Version 3.0.0-12 (I used an ubuntu kernel image) works fine by the way:
it boots, but it also succeeds in emitting AX.25 data via the baycom
driver.
