ntfs mount problems (dfly 3.0.2 + ntfsprogs)
Description
(Originally reported by Raimundo Santos)
Hi there!
Have some problem when trying to access a NTFS external hdd.
Mounted -> OK
a simple 'ls' -> OK
a 'ls -la' -> PANIC
panic: lockmgr: LK_RELEASE: no lock held
cpuid = 1
Trace beginning at frame 0xffffffe120ef06c8

Debugger("panic")
After that, tryied the TAB key in my zsh just to complete a rsync command, and panic again.
My intention is to do a backup solution with HAMMER both in the machine and in the external hdd, and mirror the machine on to the ext. hdd. But by now, the hdd is a NTFS partition.
uname -a :
DragonFly rtcprime.mondoextremoh 3.0-RELEASE DragonFly v3.0.2.55.g27ab5-RELEASE #3: Sun Jun 17 18:38:48 BRT 2012 root@rtcprime.mondoextremoh:/usr/obj/usr/src/sys/X86_64_GENERIC x86_64
(compiled yesterday)
some clue?
thanks!

Fix in commit abe9d9ec9d654eb64bf9808c39d8658c61e34ca2 on master.
Raimundo, can you please give it a try?
You can cherry pick the commit to your 3.0 branch and build the module then.
Let us know.
Cheers,

- File core.txt.2 core.txt.2 added
The same test, after cherry pick (buildworld, buildkernel, installs, and upgrade):
mount -> OK
ls -> OK
ls -la -> PANIC
dir completion on TAB -> PANIC
And the core.txt is much longer, so it is attached.
Thanks in advance for the work!

oh.... wait: the machine freezes when trying to copy a lot of data!
First tested with the initial external HDD, and now, with an internal disk with a NTFS formatted partition, at least rsync gave a panic:
The rsync command was: rsync -rltgoDuvh /mnt /var/dataholder/data_backup
And there was a panic!
The cpdup command was: cpdup -vvvvI /mnt/. /var/dataholder/data_backup
... and this just froze the system again, after coping 12GB of 69GB total.
Ah! That is in time to say that all thee tests were made with: mount_ntfs -u raitech -g users /dev/source /dest. And the copy commands issued as a normal user.
Tryied with:
rsync -rltgoDuvh /mnt/* /var/dataholder/data_backup AND mount_ntfs -u raitech -g users /dev/source /dest
SAME PANIC
rsync -rltgoDuvh /mnt/* /var/dataholder/data_backup AND mount_ntfs /dev/source /dest
SAME PANIC
Here is a partial copy of the PANIC on a core.txt file:

Raimundo,
I'm going to try to copy some gigs from a NTFS volume. Let's see if I can hit the error.
