Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I recently set up a machine to act as a remote bridge for a remote office. The machine has a couple of problems. I can workaround them, but they're annoying. It occurs to me that the cause may be that it is an SMP machine, by nature, but it only has 1 processor installed and the kernel does not have SMP stuff turned on. The two problems are: 1. When I reboot the machine, it never actually reboots. The screen clears after FreeBSD says it's going to reboot, but you never see the BIOS again. 2. Unless I comment out the psignal(p, SIGPROF); line in kern_clock.c, spurious and seemingly random SIGPROFs are delivered as the rc scripts are starting, which causes pandemonium. Does anyone think that setting up a non-SMP kernel on an SMP motherboard (but with only one processor installed) might have anything to do with this?
