I've tested it with fresh qos script, fq_codel, pppoe I get this error:
Jan 29 17:20:32 kernel: ERR[parse_qos_conf:932] Can't set new QoS conf while QoS is started!
Jan 29 17:20:32 kernel: ERR[ioctl_iqos_op_config:3592] parse qos_conf error!!
Jan 29 17:20:32 kernel: ioctl_iqos_op_config() fail!
Jan 29 17:20:32 kernel: ERR[qos_start:3344] QoS is already started!
Jan 29 17:20:32 kernel: ioctl_iqos_op_switch(1) fail!
after disabled fresh qos script I get:
Jan 29 17:54:26 rc_service: httpd 273:notify_rc restart_qos;restart_firewall
Jan 29 17:54:47 nat: apply nat rules (/tmp/nat_rules_ppp0_eth0)

I noticed on the qos statistic page that the download tab is blank after this update. upload stats working fine.
If I set qos to sfq without fresh qos script (qos statistic download tab blank too):

I never get the notification which says that fq_codel was set in systemlog
