Network bridge configuration migration

I use the latest OpenWRT snapshort (OpenWrt SNAPSHOT r16729-23f98b3eb7 / LuCI Master git-21.132.35841-3c66c5b) to build an image for BPI-R64 router board.

Installation on SD and eMMC works fine. When I try to configure the network interfaces I always get the message “. When I press continue the network config file gets broken.

The system can not start the network correctly anymore. It seems that the new style of bridge configuration (LUCI) for the network cannot be handled by the network driver.

Old style

config interface ‘lan’ option type ‘bridge’ option ifname ‘lan1 lan2 lan3 lan4’ …

work fine but LUCI cannot handle it.

Any idea’s?

After upgrading the kernel to 5.10.39 it works fine.
