  • Latest snapshot from today
  • Does not happen on 18.0.6.x
  • Router enters reboot loop

Several ways to trigger bug but it essentially revolves around bringing up a VLAN interface inside a bridge.

Some configuration examples that triggers the bug:

config interface 'lan' option type 'bridge' option proto 'static' option netmask '255.255.255.0' option ip6assign '60' option delegate '0' option igmp_snooping '1' option ifname 'lan0 lan1 lan2 lan3 lan4.12' option ipaddr '192.168.88.254'

another one:

config interface 'iptv' option proto 'none' option type 'bridge' option ifname 'eth2.12 lan4.12'

The output is:

finally I found a configuration that does not put the router in an endless reboot loop but that nevertheless crashes the kernel in the same way when issuing the reboot command:

config interface 'iptv' option proto 'none' option type 'bridge' option ifname 'eth2 eth2.12 lan4 lan4.12'

The above configuration will not crash the kernel on boot, and the iptv interface will be up. but when issuing the reboot command this happens:

finally I have tried with another port ( lan3 ) and it is the same thing.

for instance:

config interface 'iptv' option proto 'none' option type 'bridge' option ifname 'eth2.12 lan3.12'

results in the following panic on boot:
