panic in ffs_vget

This happened last night. I'm not sure exactly what triggered it. I think it
might be the weekly run becuse the daily runs apparently completed fine but I
didn't receive a weekly run output.

Just before I went to sleep I had also started transering several gigabytes of
video files to a usb hard drive. But those also seem to have completed
successfully. I'm not sure it had anything to do with the panic.

Cheers.
