fTPM/PSP NV corrupted or structure changed

Upon starting my Linux Mint 21 PC, I was greeted with this message:

New CPU installed. fTPM/PSP NV corrupted or fTPM/PSP NV structure changed.

Press Y to reset fTPM. If you have Bitlocker or encryption enabled, the system will not boot without a recovery key.

Press N to keep previous fTPM record and continue system boot. fTPM will NOT enable in new CPU, you can swap back to the old CPU to recover TPM related keys and data

fTPM stands for Firmware Trusted Platform Module and that message is featured here, in relation to Windows 10 & 11:

EDIT I have made no changes to my PC and I therefore suspect that this has been caused by an update to the Linux kernel. My CPU is an AMD Ryzen 5 5600G.

Initially I pressed N and the system booted up as normal.

I then discovered the above link which explained how to remedy the problem permanently.

NB After tapping the appropriate BIOS key at boot up, you will still be presented with the same message!

Don’t panic. Simply press N and the BIOS screens will be displayed.

Follow the instructions below for your particular motherboard.


Extract:

1. To avoid the message reappearing in the future, enter in BIOS setup and disable the fTPM in one of the following locations, according your motherboard manufacturer:

(i) Asrock: CPU Configuration > AMD fTPM Switch > Disable

(ii) Gigabyte: Advanced Mode > Settings > Miscellaneous (or “Peripherals) > AMD CPU fTPM > set to Disabled.

(iii) MSI: Advanced > Trusted Computing > Security Device Support: Disable

2. If the fTPM is already disabled in BIOS but you still receive the same message, proceed and disable also the Secure Boot. Then if the problem persists, check if there is available a new BIOS update to apply.

My motherboard is a Gigabyte, so I used option 1. (ii) above and all is now well.
