Booting ipxe from usb causes megaraid_sas driver to fail

[llnu]

We have an existing setup using the Broadcom Nics' pxe fw to chainload ipxe, then our image (devuan ascii/beowulf). It works as expected.

Our new setup has ipxe on usb, and it loads the same image via ipv6/dhcpv6 but during boot it gets stuck at: Probing EDD (edd=off to disable)
If we supply edd=off to kernel boot parameters it succesfully boots but the H800 (hwraid card) becomes unusable and it produces an error in dmesg (1).

We have tried: newer(4.19.0-6)/older kernel(4.9.0-11), recompiling ipxe/initramfs multiple times, boot uefi usb ipxe, upgrading bios/h800 fw, different hosts: dell (intel)r710/(amd)r815, multiple h800 cards

We have ran out of ideas, could somebody give us direction and pointers how can we solve this / where to continue debugging?
