Hmm.  Ok. Well, UFS_EXTATTR_AUTOSTART doesn't really need to do that on
UFS2, only UFS1, so I probably need to add a check somewhere.  It
shouldn't crash, but it also shouldn't need to be there.  If you're not
using UFS1, you can turn it off in your kernel config also, although I'd
like to make sure I fix the problem so I'll probably ask you to turn it on
briefly once I get you a patch.

Ok, that's fine; I just needed the context to know if it could be
something special about the boot-time environment.

Yeah, bizarre.  Who knows, maybe gdb got bored. :-)

I'll try to drop you a patch in the next day or so, thanks!
