Log shows hang at:

dhcp4 (enp8s0): state changed new lease, address=192.168.1.205, acd pending

Ipv6 works, ipv4 does not.

I believe this is serious enough to mask this version. It's very difficult to fix once your system ends up in this state.

Please post the output of "emerge --info net-misc/networkmanager", this may be USE flag dependant, from the linked reports it seems likely to be dependant on USE=dhclient.

The arch forum post mentioned a workaround, disabling dad-timeout, this did not resolve the problem for me.

    net-misc/networkmanager: disable ebpf due to problems for some, filter lto for clang
    
    Both bugs left open on purpose as ebpf would hopefully be fixed and re-enabled
    and LTO should be fine for clang but build system issues force us to filter it
    temporarily until a proper fix.
