So technically you're running 9.0-RELEASE UFS with 7.4-RELEASE userland. > Here are the currently mounted filesystem on the machine, as well > as mount options: > > # mount /dev/ada0p2 on / (ufs, local, journaled soft-updates) devfs > on /dev (devfs, local, multilabel) > > Any hints appreciated. My first step would be take out the journalling soft-updates to see if things improves. Could you test if this happens using brand new 9.0-RELEASE, but with journaled soft-updates disabled? (Hint: tunefs -j disable /; tunefs -n enable /; reboot in single user mode). Note that since you say 7.4-RELEASE userland wouldn't have similar issue, it might indicate a bug with the new journalled soft-updates's fsck implementation.
