Hi! Sometimes (not always) my system fails to unmount root partition while going down, it gives up with '... 1 1 1 1 1 1 1 1 1 1'. The next time it boots it complains about dirty filesystems and fsck performs its test (it always succeedes). There are no semi-dead processes (state E). Machine is pretty idle. I used this hardware with FreeBSD from the age of 3.2-RELEASE keeping it STABLE with cvsup. Never had this problem. It has appered somewhere between 4.4-RELEASE (unaffected) and 4.5-PRERELEASE (still affected). I'm sorry I do not know how can I debug this. I have DDB in kernel but not sure it is useful in this situation. It's my home machine so I would be happy to help debugging this. Here is some information about my system: # mount /dev/ad0s3a on / (ufs, local) /dev/ad0s3f on /home (ufs, local, soft-updates) /dev/ad0s3e on /usr (ufs, local, soft-updates) /dev/ad0s1 on /dos/c (msdos, local, noatime) /dev/ad0s5 on /dos/d (msdos, local, noatime) /dev/ad0s6 on /dos/e (msdos, local, noatime, noexec) procfs on /proc (procfs, local) kernfs on /kern (kernfs, local) fdesc on (fdesc) #uname -a FreeBSD D00015.dialonly.kemerovo.su 4.5-PRERELEASE FreeBSD 4.5-PRERELEASE #1: Sat Dec 22 16:07:23 KRAT 2001 root@D00015.dialonly.kemerovo.su:/usr/obj/usr/src/sys/DADV i386 Eugene Grosbein To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
