I'm running a -current kernel from a SUP around Nov 11.  I'm getting
the following panic:

panic: kernel diagnostic assertion "bn >= NDADDR" failed: file "/home/src/sys/ar
ch/i386/compile/K97/../../../../ufs/ufs/ufs_bmap.c", line 262

  My kernel config is not unusual (although it has DIAGNOSTIC and
POOL_DIAGNOSTIC enabled), but I'm attaching it to this message
anyway.

  I produce the panic reliably by:

mount /dev/wd0l /mnt
ls /mnt

  I added some printf's, and found out the assert triggers when it is
accessing inode 2 (the bad-blocks/unused inode, right?), which has a "bn"
of 0 in the call to ufs_getlbns.

  Here's the backtrace:
#10 0xc014e18c in panic ()
#11 0xc02d00b1 in __assert ()
#12 0xc024298f in ufs_getlbns ()
#13 0xc021e7a7 in ext2fs_bmaparray ()
#14 0xc021e6f3 in ext2fs_bmap ()
#15 0xc016d513 in VOP_BMAP ()
#16 0xc0246625 in ufs_strategy ()
#17 0xc016cd40 in VOP_STRATEGY ()
#18 0xc016261e in bread ()
#19 0xc0220c2c in ext2fs_read ()
#20 0xc016cfa0 in VOP_READ ()
#21 0xc021f7b6 in ext2fs_readdir ()
#22 0xc016d3a2 in VOP_READDIR ()
#23 0xc016c6e1 in vn_readdir ()
#24 0xc016c087 in sys_getdents ()
#25 0xc0264400 in syscall_plain ()
#26 0xc0100f26 in syscall1 ()

  Note that I can successfully mount some other ext2fs filesystems
just fine.  I don't know what is unique about this one filesystem that
causes the panics.  It _is_ located pretty far into a 14G disk, if that
matters:

 l:   3068352  22378608 Linux Ext2      0     0         # (Cyl. 22201 - 25244)

  Any ideas on what I can do to help debug this one?  I'll probably try
building a non-DIAGNOSTIC kernel and see if it works fine.
