One might get this impression when not installing kernel debugging
messages with RT kernels. If one does, one sees dmesg output plastered
with BUG's. Especially by modprobe when loading the nvidia module. And
there's of course these "nvidia: uh oh, sleeping while holding a lock!!"
(paraphrased) messages, too.
If you don't make backups regularly, don't use the nvidia drivers
together with -rt kernels.
This situation might be different for different kernel versions, but it
is a _real_ problem.
I always build two kernels. One with -rt and one w/o. The latter is for
gaming (naturally i have to xorg.conf's too)..
