I'm running a 2.6.12.2 kernel built directly from kernel.org
sources.  After invoking xawtv on my frame grabber card, any
time I change the video input the following messages show up
in the system log:

	Debug: sleeping function called from invalid context at
include/asm/semaphore.h:102

Any help would be greatly appreciated.  If additional info
is needed, please do not hesitate to ask.
