Resizable bar problems

[Twix1111]

Hi guys this is my first post on the forum so hopefully I’m doing it in the right place. 
I enabled resizable bar on my pc after doing a fresh windows install and all the necessary driver and bios updates. Doing this caused my nvme drive to stop working correctly. I initially thought the issue was with the drive because I was having minor issues with a couple of games crashing before I enabled resizable bar and it wouldn’t start a crystal disk mark test. Eventually I turned off resizable bar and it started working with no issues. 
hopfully this saves some people the time that I wasted and I hope it will be fixed in future bios updates.

Disabling CSM worked for me stoped all crashes especially valhalla.
