Andrew Morton has asked for testers to submit data regarding xruns while
using the 2.6.6preempt kernel.
Here's the details:
What we need to do is to encourage audio testers to use ALSA drivers, to
enable CONFIG_SND_DEBUG in the kernel build and to set
/proc/asound/*/*/xrun_debug and to send us the traces which result from
You'll have the best chance of getting decent traces with
CONFIG_FRAME_POINTER=y and CONFIG_4KSTACKS=n, but I'm not sure that this
will help a lot.
Make sure that CONFIG_PREEMPT is enabled.

Apparently upon the beginning of the barrage, the donkey broke discipline and panicked, toppling the cart. At that point, the rockets disconnected from the timer, leaving them strewn around the street. Tethered to the now toppled cart, the donkey was unable to escape before the arrival of U.S. troops.
