Description cazzantonio 2021-06-01 19:22:25 UTC 
Networkmanager build with USE="dhcpcd" crashes X as soon as the wifi tries to connect to an AP.

I run and amd564 stable system with Xfce on an intel i7-9750H laptop with an ath9k wifi card (AR9462).
More details here: https://forums.gentoo.org/viewtopic-p-8616852.html

If I rebuild without dhcpcd it works fine.

I don't even know what dhcpcd use flag do, it was simply there since long ago. Anyway, if it's available, it should generate crashes like that. Please either remove the flag or fix it.

Reproducible: Always

As we can see, syslog-ng reports it's shutting down when NM decides to renew the DHCP lease but *after* it starts anything dhcpcd related.
