[ltp] Swsusp2 and Alsasound on X40

Hi,

I have kernel 2.6.8.1 with latest ACPI patch (something like 20040815) 
und swsusp2 patch (105)running on my ibm thinkpad X40.
Suspend to ram works fine and with the help of the ibm_acpi modul 
(version 0.3) i can supend it with Fn+F4.

But, if I do a Suspend to disk with the hibernate script all is fine 
until I wake it up. All hardware is working except my Sound. i can play 
only the first one or two seconds of a soundfile and dann the speaker is 
dead :P If I play another soundfile after that, I hear two seconds of 
sound again and than sound stops.
I have an Intel 810 Soundchip with latest alsadrivers of the kernel.
What I tried to fix this was:
- Unload modul before suspend and reload after -> problem is still there
- stop all alsa userpace utils und unlaod sound before suspend -> didn't 
work
- did an alsactl power off for the soudn card and power on after 
suspend, but didn't work.

Does anybody has the same problem?

Stefan
