Hi all,

At the time of testing Audio In when I am giving the following commands

root@beagleboard /]# mount -t vfat /dev/mmcblk0p1 /mnt/mmc/cd /mnt/mmc/
[root@beagleboard /]# cd /mnt/mmc/

It is working fine. But when I am giving

[root@beagleboard mmc]# arecord -t wav -c 2 -r 44100 -f S16_LE -v k

It is showing as

Unable to handle kernel NULL pointer dereference at virtual address 00000000
pgd = c70e8000
[00000000] *pgd=87ce5031, *pte=00000000, *ppte=00000000
Internal error: Oops: 17 [#1]
Modules linked in:
CPU: 0 Not tainted (2.6.26-rc8-omap1 #1)
PC is at __wake_up_common+0x20/0x80
LR is at complete+0x3c/0x48

and a long memory map.

Can anyone help me to fix this problem??

Thanks & Regards

<truncated crash log snip>

I do recollect someone mentioning on the irc channel about alsa driver
not being stable etc.. not too sure. I suppose this issue is with the
same setup(s/w+h/w) on which you have issues with s-video too..

Could you tell us:
a) boot mode: nand/mmc?
b) if mmc how is you partitioning?
c) weblink to the kernel you are using? it would be a good idea to use
omap-linux kernel
d) weblink to the u-boot you are using?
e) weblink to the x-loader you are using?
f) weblink to the file system you are using?
g) which rev of board do you have?
h) could you give us a complete log? I would advice to copy the entire
boot sequence and attach to a text file while mailing.
i) Try to post text only format to the mailing list. it is more readable
and try not to top post[1]..
