Debug: sleeping function called from invalid context at include/linux/rwsem.h:66

[Hendrik Visage <hvjunk@gmail.com>]

I've been seeing these since around 2.6.11, but I suspected the gentoo-sources
and some nVidia errors, however, today I noticed it on a "clean" (except for the
starfire fixes discussed elsewhere) 2.6.14-rc2, and also with the
Intel 810 sound
driver :(
