netbsd-5 crash with enabled quota

Hello list,

I am using an actual version of NetBSD 5.0_BETA (amd). With enabled quota the kernel sometimes crashes with:

vnode @ 0xffff800096eade58, flags (1030<MPSAFE,LOCKSWORK,XLOCK>)
tag UNKNOWN(0), type VREG(1), usecount 2, writecount 0, holdcount 0 freelisthd 0x0, mount 0xffff800071b70000, data 0x0 lock 0xffff800096ead0

sched_sync() at netbsd:sched_sync+0x14f

Can anyone have a look at the code?

Thank you for your efforts.
