openwrt-xburst/target/linux/brcm47xx/patches-2.6.36/700-ssb-gigabit-ethernet-driver.patch
hauke 112807de3f brcm47xx: Fix boot problem with wgt634u.
Readd the workarround from the old version again which was removed in r22296 and refresh the patches.

This should close 

Thank you Russell Senior for testing.
