Yea, you'll probably want to use the noop scheduler; it is the best-tested of all the dsched modules.

I rebooted into a kernel compiled from sources I updated just a few days ago. I ran pkg_rolling-replace -nuv and it ran for a few hours, then crashed. The kernel dump is number 14 in my crash directory. The version is v3.5.0.25.g97861-DEVELOPMENT.

I also saw it freeze the first time I started a kde session after rebooting.
