Issue #2547 has been updated by vsrinivas.
Yea, you'll probably want to use the noop scheduler; it is the best-tested of all the dsched modules. ---------------------------------------- Bug #2547: crashed while doing a dry run of pkg_rolling-replace http://bugs.dragonflybsd.org/issues/2547 Author: phma Status: New Priority: High Assignee: Category: Target version: 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.
