Details

Description:

When using the Arch Netboot image, the archiso_pxe_common hook runs, prints the MAC address for both interfaces, prints configuration information for the connected interface, and never progresses past this point.

The hook does not hang if the 2nd interface is configured, or the hardware for the 2nd interface is removed from the system.


extra/archiso 27-1


Steps to reproduce:

Starting with hardware with two NICs installed
* Boot to Netboot image
* Choose mirror
* Boot Arch Linux
This task depends upon

What would be the best way to get the logs you need? I don't have very much experience in initrd-land, and the system never boots, so I'm not sure what is available or where to find it.

just like in any other place. Sure not all commands are available or with all options, but is the same. If hangs before you gat the prompt, can be a good idea to break before, or skip the hook, the run the same commands manually to see what "hang". I recommend to user forums for support request, if bug found, please back here. Thanks.

Finally got the chance to investigate this further, and it seems like the call to ipconfig on L29[1] will continue to attempt configuring an interface indefinitely if -t is not specified[2].

I will be sending a patch for this to the arch-releng ML shortly, and will add that link to this bug.

The solution ended up being a bit more involved, but these three patches should do the trick.

Glad to help. Any word on the 3rd patch to archlinux.ipxe?

It seems this commit should fix the issue
