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 ;) -- Eddahbi Karim Installation Fault
