Do you remember what the panic was?

also, something that might be useful to test is to create a directory
tree the same size as the ext2fs ones using some other fs (e.g. tmpfs)
and see what happens if the find / scans that.

(same size == same tree depth and number of names/inodes)

If that dies the problem is probably somewhere in vfs or uvm... if it
doesn't, it might still be the block driver rather than ext2fs.

If you don't object to triggering the problem on purpose a few times,
it might also be useful to try LOCKDEBUG.
