pm-suspend without suspend package -- i.e. it writes mem > state, but does some
processing before and after that. However no module loads or removes.
Particualry I have
hibernate|suspend)
service autofs stop >/dev/null
service vmware stop >/dev/null
;;
thaw|resume)
service autofs start >/dev/null
;;
While vmware is not running, autofs is.
The rest of scripts is from
http://download.opensuse.org/distribution/SL-OSS-factory/inst-source/suse/x86_64/pm-utils-0.99.3.20070618-49.x86_64.rpm
[I see now that suse added autofs stopping to their scripts too.]
Not using networkmanager.
Nothing in any pm confs, no VIDEO s3 quirks, no unload modules.
No bluetooth, no pcmcia, no batteries, no cpufreq, no backlight. -- It's desktop.
/proc/acpi/fan/*/state doesn't exist
The probably only done handling is hwclock.
