Well, I made some test using various kernel versions/configs and hsf
versions.

Kernels I used are follows:

- kernel.org  2.4.19, no patch, APM, no SMP, LOCAL APIC on
- kernel.org  2.4.18, acpi-20020726-2.4.18 and
  patch-acpi-acpi20020726-swsusp11 patches, no SMP, LOCAL APIC on

hsf drivers I tried are:

hsflinmodem-5.03.03.L3mbsibeta02061700
hsflinmodem-5.03.03.L3mbsibeta02061800
hsflinmodem-5.03.03.L3mbsibeta02062500
hsflinmodem-5.03.03.L3mbsibeta02072100

Every hsf driver is tested with both kervels.

With 02061700 I got:

error message and ppp not able to connect at all.

02061800 and 02062500 are those work better but with hangs after random
connection time. When hang occurs display goes dark (not blanck or off,
I'm able to see my desktop but it is nearly black) and speakers beep three
times.

With 02072100 isp number is dialed but modem handshake fails. My modem
emits continuous tone, the peer modem hangs up and busy tone is
audiable (if it helps I can record it to wav/mp3).

These behaviours happen with both kernels in exactly same way.
If I load hsf modules just after kernel boot *without* preloading audio
modules, machine hangs on hsfserial load.
Some times I'm able to load hsf modules without hangs even if audio modules
is not loaded, but I haven't still understood what is the "good factor".
Kernel modules loaded for 2.4.19 are:

With ACPI patched 2.4.18 there are following modules also:
ac
battery
button
fan
processor
thermal

I'll try 02062500 hsf driver disabling LOCAL APIC to see if hangs go
away.

My country is ITALY.
If I can produce some usefull debug info, please tell me what I must do.
