>Description:
A long directory listing of an HFS volume panics the kernel: (transcription by hand)

panic:lockmgr release of unlocked lock! (flags 0, sharecount 0, exclusivecount 0, recursecount 0, waitcount 0, wmesg vnlock)
db> bt
panic
lockpanic
lockmgr
genfs_unlock
VOP_UNLOCK
vput
namei
do_sys_stat
sys___lstat30
syscall_plain

The kernel is GENERIC plus hfs, DEBUG, DIAGNOSTIC minus many PCI/cardbus devices. The HFS volume is a small 8.5MB Apple_Boot partition containing bootinfo.txt, ofwboot.xcf, kernel and volume name icon. It's unlikely to matter, but both root and HFS partitions are on a FireWire disk.

>How-To-Repeat:
mount -v -t hfs -r /dev/sd0a /mnt
ls /mnt     # OK
ls -l /mnt  # panic

   Could you please send me an image of the partition?  Remote
 debugging the problem will likely be difficult.

Feedback was requested in 2007:

Alternatively, instructions for setting up a hfs volume that fails would
serve. Ideally, said instructions wouldn't require having MacOS on hand.

It's also possible that the problem no longer occurs.

 It seems I still have the installation in question, but unfortunately =
 the hard disc enclosure is currently broken.=20

 I will try to test with the old system and -current, but it will =
 probably take me some days.

 An image of the partition is available at =
 https://docs.google.com/open?id=3D0Bxn5-nQgYlfHN2c3NHEtV1pSSVctWHRGNFJaUzk=
 5QQ (netbsd_boot_part_hfs.dd.gz). As part of an APM-partitioned disk =
 (USB/FireWire) this partition lets a OF3 Mac boot NetBSD by using the OF =
 graphical boot selector (Opt-booting).

 As another datapoint I have tried a semi-recent -current with slightly =
 different hardware (G4 PowerBook), and that combination did not crash.

all this time. (!)

let's try to get this fixed.

 So it seems this bug has been fixed in the meantime? If so, I am fine =
 with closing the PR.

 Well, maybe. It's also possible that we just haven't reproduced it
 yet. How repeatable was it when you first hit it?

 It was completely repeatable (with this filesystem).=20
 I have no idea how sensitive the panic is to changes in the HFS =
 partition =97 it was a bootstrap partition containing not much more than =
 a kernel, and so it had not much churn.
