black/blue screening after installing win 11 (RAID problem)

Hello

I have a dell precision t5160 workstation here. I can install win 11 just fine. I can also install megaraid manager fine. It sees my raid controllers fine, and they see the unconfigured drives fine.

But if I make a virtual drive (just raid1) to mirror a drive, I get the blue screen the moment I create it. It reboots and tries to enter repair but immediately blue screens again with

IRQ_NOT_LESS_OR_EQUAL
storport.sys

Any thoughts?

Are you creating the RAID volume inside of Windows or the RAID controller?
If Windows, you need to be using the RAID controllers in passthrough (HBA) mode.
