[SOLVED] systemd dhcpcd crashes with coredump

I have a headless server with an Intel Atom 270 (intel D945GSEJT) motherboard with 32 bit pentum4 architecture. I use netctl for network management.

/etc/netctl/myethernet:

Connection=ethernet
Description='A basic dhcp ethernet connection using iproute'
Hostname='arch-server'
Interface=eno1
IP=dhcp
AutoWired=yes

After a recent reboot I noticed that the network interface did not get an ip address. When I configure a static ipadress network works fine. I am not sure if have done an upgrade since the last reboot.

I presume its because dhcpcd is crashing. This is what journalctl says:

     
Nov 30 21:49:20 arch-server systemd-coredump[549]: [?] Process 545 (dhcpcd) of user 0 dumped core.

What could be causing this?
Should I file a bug for systemd, and if so which info should I provide?

Re: [SOLVED] systemd dhcpcd crashes with coredump

Just use 'DHCPClient=dhclient' in your netctl profile instead (and install 'dhclient' of course). dhcpcd is known not to work since some versions.

Re: [SOLVED] systemd dhcpcd crashes with coredump

Thanks, that solved it. I also did this to be sure that dhcpcd is disabled.

#systemctl disable dhcpcd
