Hi, I'm experiencing a sort of livelock on a 6.1 prerelease box. It appears all of the IO related activity hangs but the box continues to do routing/NAT/etc for internet access from my other boxes. I can usually get the lockup to occur within about 12 hours of booting. I've narrowed down the commits to those on March 20 (kernel before then works, kernel after then causes problems) and I think the problem is geom/raid related. Besides a small gmirrored root partition the rest of my partitions are all graid3. I'm not sure what information to provide to help troubleshoot but I'm happy to do what's needed. On an unrelated note the rebuild speed was about 50% faster on my box when using the new geom/raid code introduced on March 20th. Thanks, Brad

Can you break into DDB (alt+ctrl+esc or send break via serial console) and send me the output of 'traceall' command? -- Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
