QOS breaks local DNS - v3.0-r31160M

After upgrading to DDWRT v3.0-r31160M (01/18/17), QOS breaks local DNS. I can not ping any hostname on my local network (linux or windows). I originally thought this was an IPv6 issue, but the issue persisted after disabling IPv6. I have tried different packet scheduling and different queuing disciplines with no success. Once QOS is disabled, local DNS works again. Anyone else having the same issue?
