Ok,

So... I've located the file which unlocks the problem while 1 second.
It's /proc/asound/card0/pcm0p/sub0/status.

The function in pcm.c is :
snd_pcm_substream_proc_status_read

I remove it from the routines, it doesn't settle the problem but it
removes /proc/asound/card0/pcm0p/sub0/status which let me without any
way to solve the sound problem anymore (unless kill :P).

I'll try to remove both lock/unlock irq functions and I'll tell you the
problem.

Btw I can't do any report from my kernel 2.6.2-rc1 because the ACPI
seems broken again and my modem don't work so I need to reboot on my
2.6.0 for reporting ;)
