I use WNDR3800's switch with VLANs.
After executing 'swconfig dev switch0 load network' switch hangs with
20-30% probability.
It looks like this :
{{{
root@wifi:~# swconfig dev switch0 load network_reset_switch
root@wifi:~# ping 192.168.2.1
PING 192.168.2.1 (192.168.2.1) 56(84) bytes of data.

}}}
/etc/config/network_reset_switch:
{{{
config switch
option name 'switch0'
option reset '1'
option enable_vlan '1'
option enable_vlan4k '1'
option max_length '3'
config switch_vlan
option device 'switch0'
option vlan '1'
option ports '0 1 2t 5'
config switch_vlan
option device 'switch0'
option vlan '2'
option ports '2t 3'
}}}
Only reset operation causes problem. When reset is 0 switch does not
hang.
When switch is hang 'swconfig show' outputs correct configuration. No
switch specific dmesg can be seen.
Problem is very painful for me because reset is executed on every boot.
I had to write cure script that pings nearby hosts and reset switch until
its working.
