[ipxe-devel] blank screen, then back to grub. What to do next?

[Ian Kelling]

Wondering how I would go about debugging this?

Ipxe version is from debian package 1.0.0+git-20150424.a25a16d-1,
the relevenat grub2 command to load ipxe is this:
linux16 /boot_debiantesting/ipxe.lkrn

The screen goes black for a few seconds, then goes back to grub.
This is on an x200 laptop with libreboot bios.
The ethernet card is intel 8086:10f5, listed on the expected to work
page.
