"zfs scrub" causes kernel panic with FreeBSD 8.0-RELEASE amd64. Test system installed via VMware Fusion 3.0 using 1 processor and 2GB of RAM. Several parameters for vm.kmem_size, vm.kmem_size_max were tried with no differences. The panic doesn't seem to happen if ZFS is backed by IDE hard drives. How-To-Repeat: After clean install, added "zfs_enable=YES" to /etc/rc.conf. Went through ZFS tutorial at: http://flux.org.uk/howto/solaris/zfs_tutorial_01. This creates two 128MB files and creates a ZFS mirror pool backed by the two files. Tutorial then tries to demonstrate a ZFS failure mode. Commands as follows: zpool create trout mirror /home/ocean/disk1 /home/ocean/disk2 mkfile 32m /trout/foo dd if=/dev/random of=/home/ocean/disk1 bs=512 count=1 zpool scrub trout At this point, the kernel panics.

^Triage: I'm sorry that this PR did not get addressed in a timely fashion. By now, the version that it was created against is long out of support. As well, many newer versions of ZFS have been imported. Please re-open if it is still a problem on a supported version.
