I also encountered the ffs panic. It seems to happen on bootup after
a kernel panicked and a filesystem became unclean. It's not related to
neither NFS nor re(4). I guess it's because of a recent ffs/vfs change.

Oh, I have no idea when using X because I don't use X daily. I guess you
need to switch to a console beforehand to see DDB on a kernel panic.
