I have tried to apply the patch manually but I couldn't because I am on kernel version 2.6.22.1. Is the patch available for my kernel version? How should I go about it? One observation I had was when I removed "SNDRV_PCM_INFO_MMAP" from the "pcm_hardware_playback", the kernel stopped crashing. It gave me some error and returned.

It would be really helpful. You can try my experimental tree: git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-unstable-2.6.git Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
