After some debugging I've found that there is actually two problems:
First - with switching hardware (Inter 460t with 802.1Q capable
firmware), It fails correct deliver broadcasts from trunked port to
untrunked port after untrunked port goes down and then up.
Second - with arp utility, it can't handle arp entries on vlanX
interfaces correctly, there is simple patch for fix arp behavior:
diff -N -u arp.c.orig arp.c
