devkit8000-eclair-x4 crashed when playing audio with ALSA #132

I use devkit8000-eclair-x4

When playing audio with ALSA  use the command:

# alsa_aplay test.wav 

just a few minutes, the board crashed.

I think there has memory leak in ALSA.

What can I do to fix it?

Thanks!

yours, Allen.

Post the relevant dmesg and logcat output would be helpful :)

and  I use USB to connect,  and adb shell to debug. The board will halt.

but I use serial port at COM1, it is ok. 

Why?

I am sorry for describing error. It's halt, not crash.

So I can not see any debug informations.

Maybe it's a softlockup. If you wait it for about 20~ seconds there might be 
output like

  BUG: soft lockup - CPU#0 stuck for 61s! [swapper:0]
  Last softirq was rcu_process_callbacks+0x0/0x38

I think it's the problem caused by the USB.

When I use USB to connect, The board will halt.

and I use serial port at COM1, it,s all right.

We tend to work on omap3-2.6.32 branch for such problem.
