Looks like I'll be staying on Catalina for my 5.1 Mac Pro.

Big Sur has been nothing but bugs anyway.

Starting with the super slow boot time on a 2019 iMac 27" because Big Sur is not optimized for APPLE FUSION drives

no USB issues, using a ASmedia 1142 card

Thanks for the reply! How about cards which use the FL1100 chipset (I think the one used in nMP) such as inateck cards?

Thanks once again!

I test booted an 11.3 B7 USB drive (install performed on another machine) on my 5,1 with Innateck USB3 running 11.2.3 and OC. The system hangs during boot and eventually craps out (prohibited symbol) if anything is plugged into the USB 3 card during boot. I can see it enumerating devices plugged in to the card when the hang occurs (I run my system with verbose boot permanently enabled in OC config). If I unplug everything from the card, it boots successfully, and once booted I can plug devices into the card and it appears to work.
 
I have two 5,1 machines - primary and test. Test machine has an SSD in drive bay 1 with OpenCore 0.6.8 and Mojave, an HDD in bay 4 with 11.3b7, and a SATA SSD on PCIe card with 11.3b7. I removed the USB3 card for testing 11.3. Upgrading the HDD in bay 4 works every time, as does booting, every time. The SSD on PCIe took 7 restarts to get b7 installed, and boots occasionally, but most of the time ends with the prohibited symbol. I don't think this is new information, but since there's been a lot of talk about USB3 lately, wanted to provide my results with no USB3 card installed.
 
@VitaminK I tried beta 7 with the SSDT NVME remaps and it still panics. I tried at least 7-8 reboots all with panic. I am not even sure it depends on anything in the OS itself, because the panic log states that it occurred prior to OS initialization. Might be the NVME driver in the firmware?

Perhaps this could be confirmed by using the shell in OC to unload the driver and then booting 11.3 from a SATA drive.

Code: 
unload A4
A4: Image(51116915-C34B-4D8E-86DB-6A70F2E60DAA) DriverBinding ComponentName
Unload driver image (y/n)? y
unload driver image error - unsupported
 
If the problem arises also with USB 3 pcie cards when drives are plugged into them, wouldn't it be safe to assume that this is not an nvme problem only but one affecting any type of storage going through pcie?

New 11.3 Beta is out. Fingers crossed!

Tested. Same kernel panic. On the first reboot tried booting through the newly created Macintosh HD with panic. The next boot was from the original boot selection for Big Sur. It indicated installation of files, but upon booting it was still 11.2.3. Macintosh HD option is still there. This time I only tried regular update rather than installation from a complete installer.
 
11.3 beta 8 boots , but has issues

Audio, Sata & Ethernet still supported

So regardless of performing a full install or an update it panics? Not good...
 
Is this the point that everybody starts experimenting installing 11.3? Would turning the vmm flag on make any difference?
