As described in earlier reports, 9-STABLE sometimes cannot halt or reboot properly. FreeBSD 9.1-PRERELEASE #0 r241866: Mon Oct 22 16:28:47 CEST 2012 All ZFS file system, no NFS mounts. The problem occurs after updating sources and rebuilding world for some reason the I suspect is connected to the file system. "shutdown -r now" or "halt -p" will stop after "Syncing discs" forever. It is seen here on various HP boxes, DL360 G4, G5, XW6600 are examples. Issuing a "shutdown -n -o -r now" works however and I assume this is not too harmful with ZFS? Setting sysctl hw.usb.no_shutdown_wait=1 does NOT fix the problem as described in http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/167685 Should I file another bug or add to the existing? Would it be useful to build a debug kernel, if yes, including what? Thanks! //per
