[DragonFlyBSD - Bug #2388] ntfs mount problems (dfly 3.0.2 + ntfsprogs)

[Raimundo Santos via Redmine <bugtracker-admin@xxxxxxxxxxxxxxxxxxxxx>]

Issue #2388 has been updated by Raimundo Santos.

File 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!

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

Xfast_syscall() at Xfast_syscall+0xcb 0xffffffff807448eb 
 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 :

some clue?
thanks!
