netbsd-5 crash with enabled quota

[6bone%6bone.informatik.uni-leipzig.de@localhost]

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>)

Can anyone have a look at the code?


Thank you for your efforts.
