Bridgeing VLAN and phisical port

I bridged phisical interface with VLAN interface on my RB493G and everything works fine, bat after router reboot bridge port disappear. What can be a problem?

 #    INTERFACE               BRIDGE               PRIORITY  PATH-COST    HORIZON
 0    vlan100                 LAN+WLAN                 0x80         10       none
 1    wlan1                   LAN+WLAN                 0x80         10       none
 2    vlan200                 ether5+VLAN200           0x80         10       none
 3    ether5                  ether5+VLAN200           0x80         10       none

Ether 2 is trunk port:

 int vlan pr
Flags: X - disabled, R - running, S - slave 
 #    NAME                     MTU ARP        VLAN-ID INTERFACE                  
 0 R  vlan1                   1500 enabled          1 ether2                     
 1 R  vlan100                 1500 enabled        100 ether2                     
 2 R  vlan200                 1500 enabled        200 ether2                     
 3 R  vlan300                 1500 enabled        300 ether2                     
 4 R  vlan400                 1500 enabled        400 ether2

Which port “disappeared”? The WLAN? Make sure there are clients on it.

ether5 and VLAN200 from bridgeether5+VLAN200, VLAN100 and WLAN from bridge LAN+WLAN.

What RoS version are you using?

6.11

I think this is a bug in RoS 6.11. If i remember correctly I read about it on the ros 6.11 release thread. Problem with bridges.
