"try to free memory without signature"

[dcnieho]

Thanks for that tip. I have already tried resetting BIOS, reflashing it, etc.

The machine (and all the others) do boot from undionly.kpxe from boot.ipxe.org. When i drop to shell and issue ifstat, I notice that there is a difference between the undionly.kpxe supplied with clonedeploy and the one i just downloaded. the clonedeploy one is a bit over 300kb and ifstat reports "using i210 on PCI02:00:0" whereas the fresh undionly.kpxe reports "using undiononly on 0000:02:00:0"

So i (randomly) guess quite some custom config went into the clonedeploy-supplied one (and perhaps the file is misnamed?). I'll try to build a clean undionly as i need to embed a script i think. Will report back (and would be happy to hear your insight with this new info)

Edit
Ok, i have built undionly.kpxe with an embedded script.
This one works fine:

Code:

#!ipxe

dhcp
chain http://boot.ipxe.org/demo/boot.php

But this one does not:

Code:

#!ipxe

dhcp
chain pxelinux.cfg/default.ipxe

I get http://ipxe.org/err/3c0920 after the dhcp command completed fine (it seems).
If i use a freshly self-compiled undionly without embedded script, get stuck in a boot loop, break to shell and issue the above two commands manually, things work fine. My DHCP server does provide a next server. How would I debug this? / Do you have a hunch what may be up?

Thanks a lot!
