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).. Flo -- Palimm Palimm! http://tapas.affenbande.org
