I'm following this guide to reflash my IBM M1015 card to IT mode: https://www.servethehome.com/ibm-serveraid-m1015-part-4/

The motherboard is EPYC3251D4I-2T

After completing this step

Code:
megarec -writesbr 0 sbrempty.bin
megarec -cleanflash 0
<reboot, back to USB stick >
I can't boot. The system hangs on

Code:
DXE--PCI Bus Enumeration...
message before I can pick a boot option or enter UEFI setup.

When I remove the card the system boots normally, but without the card I can't finish loading the new flash.

How to proceed with this?

PROTIP: Don't try to bypass this issue by hot-plugging the pcie card after boot sequence is completed - you will likely fry your card. :(

I've ordered another IBM M1015 card, will try to flash it on another machine next week.
