Hi,
I just installed a vanilla 2.6.26.1 kernel and sound works flawlessly here.
Maybe Ubuntu messed something up, maybe it's just that it's a newer version,
I don't know.
However, now the modem doesn't work anymore.
I patched the sound driver and compiled the modem driver. The modules load
without any problems:
# modprobe agrmodem
# modprobe agrserial
#
dmesg says:
agrmodem: module license 'Proprietary' taints kernel.
* Hello Agere Driver **
Loading module Agere Modem Controller driver version 2.1.80 (2007-10-1)
ttyAGS3 at I/O 0x4 (irq = 22) is a AgereModem
Loading module Agere Modem Interface driver version 2.1.80.0 (2007-10-01)
So I create a symlink to /dev/modem and try running wvdial:
# ln -s /dev/ttyAGS3 /dev/modem
# wvdial
- --> WvDial: Internet dialer version 1.60
Segmentation fault
dmesg shows some rather nasty looking errors:
==> codecType = 0x32

If I try running wvdial again it just prints:
# wvdial
- --> WvDial: Internet dialer version 1.60
and stays running. Not even kill -9 will terminate it. It does not print any
further messages to dmesg.
With the Ubuntu kernel the modem driver worked, even if the sound driver was
messed up. Any ideas what to do about this now?
Beste regards,
Victor
