I'm running a 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

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