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.
[root@OMAP3EVM bin]# [root@OMAP3EVM bin]# ./pcm -f cd -r 1000 Playback device is plughw:0,0 Stream parameters are 4000Hz, S16_LE, 1 channels Sine wave rate is 440.0000Hz Using transfer method: write ALSA lib pcm_plug.c:773:(snd_pcm_plug_hw_refine_schange) Unable to find an usable access for 'plughw:0,0' Rate 4000Hz not available for playback: Invalid argument Setting of hwparams failed: Invalid argument
Thanks and Regards, Anuj Aggarwal

Can you point me to any particular git tree which I can download and apply the patches directly, instead of committing any silly mistake? 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
