Re2: hsfmodem-7.47 driver blocks suspend to disk on SuSE 10.1

Hi,

I played a little with the /etc/sysconfig/powersave/sleep file.

First I modified /etc/init.d/hsf script replacing hardcoded 'exit 3' with
'exit 0'
for 'status' option, to make it executed during suspend process (it will be
nice
to have real 'status' option).
Next I added 'hsf' after all default init scripts to the entry:
SUSPEND2DISK_RESTART_SERVICES="slmodemd irda upsd apcupsd hsf"

This made suspend to disk working, but with two limitations:
1. Suspend fails if call is active (more or less expected by me)
2. After returning back from suspend, modem is not working - log file
   /var/log/suspend2disk.log shows that /etc/init.d/hsf was started.
   Also /dev/modem and /dev/ttySHSF0 exist.

After full system reboot modem works correctly.

I also tried with UNLOAD_MODULES_BEFORE_SUSPEND2DISK
entry but result was the same (because lack of time I declared only
'hsfosspec' and 'hsfsoar' after default modules and additional 'natsemi'
for my ethernet).

Any suggestions how to make it working after returning back from suspend?
For quick test I used: stty -a </dev/modem which
returned parameters if modem worked or error message
if not.

Regards
Wojciech

Hi,

as a workaround, did you tried to use the 'hsfstop' command before you
suspend the laptop to see if there is a difference?

Linuxant is working on improving suspend support for the driver and it
is possible that a future version of the driver will offer better
suspend support for the kernel used and your system.
