boot command hangs

[bacaw]

Sorry, extra information:

Binary: undionly.kpxe
ifstat:

Code:

iPXE> ifstat
net0: 00:0f:53:4c:d5:90 using undionly on 0000:d8:00.0 (open)
  [Link:up, TX:10 TXE:1 RX:17 RXE:5]

  [RXE: 5 x "The socket is not connected (http://ipxe.org/380a6001)"]
iPXE> ping <gateway>

..etc

Chaining boot.ipxe.org/demo had the same result (flashing cursor indefinitely, after the '..ok' messages for vmlinuz and initrd loading)

ipxe.pxe just plain failed to load..

Code:

From looking at https://ipxe.org/appnote/hardware_drivers, my driver is sfc_hunt, so I've used DEBUG=sfc_hunt:3 while compiling my ipxe images, no extra output seen when booting any legacy bios images though..

Interestingly if I try ipxe.efi (64bit) it works, and my original fedora28 kernel boots at least, my build isn't setup for UEFI so it hangs later on due to other problems. I just had to add initrd=initrd.img to the ipxe script kernel line to get it to boot. I see some coloured sfc_hunt messages when ipxe.efi is attempting to DHCP on all the interfaces.

So, seems its a UEFI vs legacy problem? Still unknown if it's the BIOS at fault or iPXE, or even the Solarflare firmware.

Thanks for your reply!
