Hello, I've got a 6.0-RELEASE machine and am going to compile a new kernel on it. I've got a few questions as to the best options. This is a single-processor machine, going to run only 6.0. Which of the schedulers should i use SCHED_4BSD or SCHED_ULE and do i need the PREEMPTION option? And the COMPAT_* options, 43, i know i need that, do i need the 4 or 5 options? And what purpose does device apic serve, do i need this? And is quota now used by default or do i have to compile it in? When booting this machine with GENERIC i'm getting some bootup messages i find slightly disturbing: ahc0: (GIANT-LOCKED) and a little later: no suitable dump device was found this is on a geom gmirrored system updated from 5.4-RELEASE-p6 to 6.0-RELEASE. Thanks. Dave.
