Unable to remove ZIL from ZFS v28

[Nicholas Radonicich]

Hello, I tried to remove the log device I was using testing ZFS, when I
ran zpool remove tank ad10 the system became unresponsive. I left it
overnight and no change thinking that the system was working things out.
Below is my zpool info, both the cache and log drives are basic SATA
discs. On reboot of the system I was unable to get past loading ZFS
without booting into singleuser and putting the log device offline. Once
offline (and unmounted) if I try to remove the log device the system
still hangs. I'm currently scrubbing the system but any help on getting
the device removed would be appreciated... or if more information is
needed that is no problem either.
