Hi,

I compiled 2.6.0-test9 on my desktop last night. Not too many problems
so far, but this debug trace caught my attention:

Debug: sleeping function called from invalid context at include/asm/semaphore.h:119
in_atomic():1, irqs_disabled():0
Call Trace:

It looks ALSA related to me, the soundcard I use is a Midiman
Audiophile 2496, which uses the ice1712 driver.
