Hi Ante, The best thing to do here is to select the kmdb boot option from the bios menu. This will then let you end up in the debugger when you take the nmi. When you're at the first prompt, you'll want to use ':c' to continue. At the nmi, the most useful things to get started would be the following commands: '$C' '::stacks -m xhci' '::stacks -m usba' '::prtusb' Once we get that, I'll see if we can dig further into what SMCI is doing with that BIOS option as well and reach out to them.
