Hi,
Just been trough ~5+ hours of bisecting and eventually actually found
the culprit =)
commit fb420d5d91c1274d5966917725e71f27ed092a85 (refs/bisect/bad)

tcp/fq: move back to CLOCK_MONOTONIC
[--8<--]
So this might be because my setup might be "odd".
Basically I have a firewall with four nics that uses two of those nics
to handle my normal
internet connection (firewall/MASQ/NAT) and the other two are assigned
to one bridge each.
The firewall is also my local caching DNS server and DHCP server,
which is also used by the VM:s...
But with 4.20 DHCP replies disappeared before entering the bridge - i
couldn't even see them in
tcpdump! (all nics are ixgbe on a atom soc)
I'm currently running a kernel with that patch reversed but I'm also
wondering about possible ways
forward since I'm reverting a fix from someone else...
