Hi,
I tried installing using Arc Loader on a Supermicro A1SRM-2758F.
There was various super odd problems, like a kexec boot working well but otherwise losing link on the NIC interfaces, and even USB needing to be re-plugged to be bootable...
I was - or am - about to throw away the board.
In arc loader I had zero issues when it was running, but when rebooting into the final thing the NIC Ports would just go offline.
(kexec was the magic trick, but only ONCE... So I finished an install and then it was dead again)
At last, I found this https://unix.stackexchange.com/questions/72625/why-is-usb-not-working-in-linux-when-it-works-in-uefi-bios#comment522529_72698 and then this

This special Atom model with QAT and i350 NICs and all the other fancy stuff didn't have VT-d stuff.
Is there a way I can pass iommu=soft reliably to the DSM kernel?
