 Am I right in thinking this means it croaked in whatever function is
 at 0xf0006254 (inside a module?), which was called from offset 0x204
 into ufs_lookup?
 
 I don't see anything in ufs_lookup, or at least anything near enough
 to the top to be at offset 0x204, that ought to be a call into a
 module, so I'm not sure what to make of this.
 
 Anyone with sparc knowledge want to comment?
