Because it never reaches the code section were the crash happened before. 
Please use the patch "Don't validate hardware address of batgat gate0 device" 
to reenable batgat on post 2.6.23 kernels. If you want to help to find the 
problem of the "original" crash, please apply the patch inside this mail.

looks like OpenWRT build with latest trunk r1112 built seems to be pretty
functional no issues so far, at least on UBNT
