vinum lock panic at startup -current

I just cvsuped -current this afternoon to get about 1 weeks updates. 
After that the kernel panics booting starting vinum.  I removed the one
vinum volume (reformated as UFS2) I had for testing. And it still panics.
 I changed the /etc/rc.conf 
start_vinum="YES"  to NO and can start ok now.

Anyone else seeing this?  Is there a fix for it?
