Could you post the result of:
cat /etc/config/sqm
from the router, please? And the output of
/etc/init.d/sqm stop ; /etc/init.d/sqm start
this might give me a clue where to look...

This command never completes. I added -x to simple.qos and the RTNETLINK
is from:
+ /usr/sbin/ip link add name ifb4eth0 type ifb
RTNETLINK answers: File exists
and the last commands that execute are:
SQM: STAB: stab mtu 2047 tsize 512 mpu 0 overhead 42 linklayer ethernet
+ echo stab mtu 2047 tsize 512 mpu 0 overhead 42 linklayer ethernet
+ get_cake_lla_string
+ STABSTRING=
+ [ tc_stab = cake -a ethernet != none ]
+ sqm_logger
+ logger -t SQM -s
