X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 09 Mar 2004 07:19:12 -0000 At a certain point after booting my SMP 5-current box gets all weird, typically I see 50%+ time spent in interrupt. If I run "top -S" I typically see one of the ithreads using 50% cpu. I'm trying to figure out what it's doing, what has gone wrong etc. Are there any sysctls to look at or things I can do to diagnose this? (also I my laptop still can't boot with top-of-the-tree current) :( -- - Alfred Perlstein - Research Engineering Development Inc. - email: bright@mu.org cell: 408-480-4684
