Apologies for the rough format here, I had to take a picture of
this failure because I didn't know what else to do.


I'm building off of the GitHub freebsd.git mirror here, and the
latest commit in the tree is neel@'s "Add an ioctl to suspend.."

My dmesg/pciconf are here:
As linked before, the dmesg and `pciconf -lv` output can be found
here: <https://gist.github.com/rtyler/1faa854dff7c4396d9e8>

Also in addition to the photo from before of the panic, here's
another reproduction photo:
Are you or have you even been running with any ZFS-related kernel
Negative, I've never run any specific ZFS patches on this machine (or
any machine for that matter!)

One other unique clue might be that I'm running with an encrypted
zpool, other than that, nothing fancy here.

I've upgraded my machine to r264387 and I still experience the issue, here's the latest pretty picture of my panicked laptop :) <https://secure.flickr.com/photos/agentdero/13880032704/>

The issue still seems to stem from a failed assertion in zap_leaf_lookup_closest() (http://svnweb.freebsd.org/base/head/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/zap_leaf.c?revision=249195&view=markup#l446) but I'm not sure which assertion might be failing.

This is somewhat problematic because I cannot perform *any* FS operations with the tainted directory tree, not even a `du -hcs *` to find out how much space I can never access again :P

I can reproduce this consistently, if anybody has the time to get onto IRC (rtyler on Freenode and EFNet) and debug this, I can certainly act as remote hands with kdb to help ascertain more information about the panic.
