 If you disable just UFS_EXTATTR_AUTOSTART, does the panic go away?  The 
 autostart routine relies on reading directory data (or at least, performing 
 lookups) during the mount process.  While it shouldn't be running on UFS2, it 
 could be that it is, and if something has changed in the mount process so that 
 reading directories that early is no longer functional, it could be that this 
 causes an incorrect reporting of on-disk corruption (i.e., it could be a data 
 structure initialization problem or the like).
