Public bug reported:

here is what is going on starting with my system...

MSI MPG B550 GAMING PLUS with BIOS version 7C56v18
AMD Ryzen 5 5600x
16 Gig DDR4 3200 ram
XFX AMD Radeon rx6600 (monitor connected to this card)
Nvidia GTX1050 (tried both with and with out this card installed,Same 
results... even with this card as primary)
5 ACHI SATA III drives (all GTP partitioned) sda1 is a 900 meg EFI 
partition,sda2 Windows 11 partition, sdba kubuntu partition.  sde has the 
swapfile partiton

I have a dual boot system with Win 11 pro, Kubuntu 21.10

Secure boot is enabled (the conical key is removed from the forbidden
TPM list and added into the allowed list) MSI in their wisdom put the
conical key into the forbidden TPM list in their BIOS by default

In the Kubuntu 21.10 installer I get to the ok button just prior to the
disk set up screen with out issue.  it hangs and will not continue to
the disk management screen at all no mater which options are
selected.(waited over 12 hours of system busy mouse icon)

the Kubuntu 20.04 installer works as long as secure boot password is set
up and the download updates, and 3rd party drivers boxes are not
selected. (have to use safe graphics, then in rescue mode enable network
and fix dpkm packages for full graphics support for the AMD card. then
do the release upgrade command to upgrade to 21.10)

to further test I installed vmware workstation and set up a virtual
machine as if it was for windows 11 but installed kubuntu 21.10
instead... no problems... the vmware virtual machine only allows for
installation on a NVMe drive interface not a SATA interface so unable to
test with only a SATA hard drive on the vmware virtual machine like my
system has.
