"pump" times out -- extend a few seconds more?

Fri Feb 23 20:37:41 UTC 2007

It's applicable because you said your problem was:

> the network needs to "come up" before Anaconda times out.

That's exactly what nicdelay is supposed to help you with.  The problem
is, it takes ~ 30 seconds for the nic to negotiate with the switch.  By
delaying bringing the nic up until enough time has passed that the
negotiation has taken place, you should then be able to configure the
nic, get your kickstart file, and be off and running.

Now, I say "supposed" to, because I've never had to use it, and heard
mixed results from those who have.

Remember, the nic gets completely cycled and needs to renegotiate 3
times during a build:

at power on
when getting the kickstart file
when starting the build

I did a cursory search of nicedelay and I don't see how it is applicable
for my situation...  Maybe I just don't know how to use it.

Portfast is enabled.

I tried the eth0_ethtool option, but that didn't appear to help.

I thought about placing the ks.cfg files in the initrd, but didn't
really want to go there.

Thanks
