 Hi,
 
 I think i've also the bug with panic: ffs_blkfree but my panic is :
 
 fsync: giving up on dirty
 0xc3ff3114: tag devfs, type VCHR
     usecount 1, writecount 0, refcount 771 mountedhere 0xc3fac300
     flags ()
     v_object 0xc1045600 ref 0 pages 3836
      lock type devfs: EXCL (count 1) by thread 0xc41a6690 (pid 1831)
   dev ad4s1f
 fsync: giving up on dirty
 0xc3ff3114: tag devfs, type VCHR
     usecount 1, writecount 0, refcount 771 mountedhere 0xc3fac300
     flags ()
     v_object 0xc1045600 ref 0 pages 3836
      lock type devfs: EXCL (count 1) by thread 0xc41a6690 (pid 1831)
   dev ad4s1f
 dev = ad4s1f, block = 1, fs = /usr
 panic: ffs_blkfree: freeing free block
 
 I've got this, two times i think when rebuilding the kernel, this is a
 FreeBSD 7.2-RELEASE installed last day in 7.2-RC2 and recompilled in
 7.2-RELEASE.
 I can't reproduce this bug for the moment...
 
 Is it related ? Any informations about this bug ?
 
 Thx.

 I just saw this on AMD64 on FreeBSD 8.0.  I'm kind of surprised to see this
 still lingering around.  Should I continue this problem report or submit a
 new one?
