rerwin, let's take the technical discussion of ALSA-compatibility offline. I have sent you a PM.

peebee,
I have something for you to try. Tempestuous sent me a dot-pet of the ALSA 1.0.21 library and utilities that I have tested on my PC. The same test as before, forcing loading of agrmodem, produced a better-looking set of messages -- and no distress calls!
    Sep 23 17:38:30 puppypc user.info kernel: usbcore: registered new interface driver agr12dec2006
    Sep 23 17:38:30 puppypc user.warn kernel: serial8250_register_ports: BaseAddress 0x0400 Irq 3
    Sep 23 17:38:30 puppypc user.info kernel: ttyAGS3 at I/O 0x400 (irq = 3) is a AgereModem
    Sep 23 17:38:30 puppypc user.err kernel: agrserial - ret_val 0, call: lt_modem_ops.init_modem
    Sep 23 17:38:30 puppypc user.info kernel: Loading module Agere Modem Interface driver version 2.1.80.0 (2007-10-01)

This suggests that the package may solve the problem. However, it restores ALSA 1.0.21 for everything, so new features provided by 1.0.24 will be lost.

I have modified the package slightly, to add scripts to deal with the fact that lupu puts 2 files in /sbin, while the package has them in /usr/sbin. If you uninstall the package, the mods will be undone. The package can be installed on top of everything else, so you need not start afresh. Here's hoping.

So so sorry Richard - but I still get a crash even with the alsa 1.0.21 pet

peebee,
I am surprised by the failure of the ALSA 1.0.21 package to resolve the crash problem. The idea was to have all parts -- library, utilities and driver -- at the same version. If the agrsm driver was coded for 1.0.20, 1.0.21 must be too different for it to handle.

Although I doubt it will help, you might also try installing the new compiled version of the ALSA 1.0.24 driver into a normal lupu 528, to match the library and utilities there. But since it crashes with 1.0.21, I don't expect any better from matching ALSA 1.0.24 components, either.

I think we will have to wait for the agrsm driver maintainer to upgrade it to at least ALSA 1.0.24.

Hi Richard

I guess the advice we should give anybody with the AGERE HDA modem is to use Wary in the first instance.

If they really want lupu or slacko then it is possible to switch their kernels to use the wary kernel as described in:
http://www.murga-linux.com/puppy/viewtopic.php?t=60180

I've put the kernel from wary5.1.103 into both lupu528 and slacko4.99.7 today and both seem to work fine AND have a working modem - see the attached screen dump.

I'll put this thread back to CLOSED.

Cheers
peter
