DHCP fails at boot, works with dhcpcd from serial terminal

[radengr]

I have a Dockstar that I am trying to get set up as a CUPS printer server. Right now it has a stock archlinuxarm install after following the instructions on this site.

I can only connect to it on the network once every 6 boots or so. So I popped it open and hooked up a ttl level serial cable and I think I have tracked down the issue. While booting it takes a while at the "starting network" before continuing; but it does not seem to get an ip address (mac redacted):

$this->bbcode_second_pass_code('', 'eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 metric 1
inet6 fe80::210:75ff:fe1a:7ba prefixlen 64 scopeid 0x20<link>

TX packets 7 bytes 860 (860.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device interrupt 11

lo: flags=73<UP,LOOPBACK,RUNNING> mtu 16436 metric 1
inet 127.0.0.1 netmask 255.0.0.0

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 4 bytes 260 (260.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
')

I can either set an ip via the serial console or use dhcpd and get an ip right away (and of course connect from the network again):

$this->bbcode_second_pass_code('', '

Did I do something dumb? And more importantly... what can I do to fix this? I don't want to have to use the serial console to set up the network every time I boot (also, I would like to put the thing back together before I lose the top!)

EDIT: Changed topic to be a little more informative and fixed a couple of typos.

I'm not sure if this is the right way to fix this, but it seems to be working?

I edited "/etc/conf.d/dhcpcd" and changed:

$this->bbcode_second_pass_code('', 'DHCPCD_ARGS="-q"')
to:

$this->bbcode_second_pass_code('', 'DHCPCD_ARGS="-q -t 120"')
I've been rebooting and so far I have an IP everytime. I just hope that it keeps working once I put it back togeather
