After kldunloading xfs, the kernel crashes.
Nothing happens directly after unloading but simply entering a character at the shell will trigger a kernel panic.

 Hello Timothy,
 
 Can you also tell how you are using XFS? If you use it as primary
 filesystem the resulting crash is not weird or so ;-)
 
 Please do note on forehand that 7-CURRENT is not yet supported
 and seen as development platform, so this could be the result
 of development instead.
 
 Though I have CC'ed the last one touching the XFS files in the
 mailing..
 
 Hope this helps!

 Just wanted to check out the -CURRENT xfs support, not using it as my primary 
 FS at all :)
 I can make an md, partition it with xfs and mount it, but as soon as I unload 
 the module, the system hangs.
 So I tried to reproduce it and as it seems you don't even have to do anything, 
 just load the module, unload it, type something on the console and it 
 crashes.

 I know, thanks for the warning though.
