HI everyone,

I tried to install btrfs on my root filesystem (/), this is what I did :

install debian with :
/boot (ext2) (for grub),
/ (ext3),
swap,
grub on MBR.

compile the 2.6.31-rc4 from kernel.org with btrfs support
test the new kernel by rebooting (worked fine)
install btrfs-tools from debian sid repository (0.19-2)

boot on a ubuntu 9.04 live cd

Issue:

If I play the wav file using "aplay", underrun error occurs.

I am suspecting the issue in driver or in kernel code.

I am using the following setup:

a) Application and Library:
aplay in alsa-utils-1.0.16 and alsa-lib-1.0.16.
b) Platform: imx27
c) kernel: linux-2.6.25

Hardware & Software parameters for aplay:
