The TNF sparc testbed recently started panicing with a similar error in
every test run:

  sbin/resize_ffs/t_grow_swapped (445/663): 4 test cases
      grow_16M_v0_65536: ffs_newvnode: ino=45826 on /: gen 65327e67/65327e67 has non zero blocks 180 or size 0
  panic: ffs_newvnode: dirty filesystem?

The strange thing is that this problem seems to have started soon
after your report, not before it as I would expect if it were also the
cause of your crash.  The filesystems involved are all newly created
in each test run.
