Yes, but more information is definitely need. Few things before that:
- Can you try to compile a latest kernel from netbsd-5 branch? There is one
deadlock fix in VFS layer.
- Can you get into DDB and get a backtrace of LWPs which are stuck?
- Have you tried to leave only one CPU online and see if problem still occurs?
See cpuctl(8) man page.

removed in -current, and wont be in further releases.
