ZFS race condition?

[Marcel Moolenaar]

I've started a little ZFS test on my SMP box to see how
healthy it is and I ran into the following:

VNASSERT failed
0: tag (null), type VNON
     usecount 1610614632, writecount 0, refcount 1006665672  
mountedhere 0
     flags (VV_ROOT|VV_TEXT|VV_DELETED|VV(0x4e800000)|VI_MOUNT| 
VI_DOOMED|VI_FREE|VI(0x7c090206))
      lock type (null): EXCL by thread 0 (pid 0)

panic: No vop_lock1(0, 0xe4a4682c)
cpuid = 0
KDB: enter: panic

Something (read: usecount and refcount) tells me that
we may have a race condition...

Anyone else playing with ZFS on PowerPC seeing this?
