auto LUKS unlock with FIPS enabled

[atgmtg]

I have a system with Ubuntu 22.04 installed, FIPS mode needs to be enabled. I have two disks encrypted with LUKS that I'd like auto-mounted on boot via TPM. I am able to get this to work with FIPS mode disabled, but when I enable FIPS mode the auto-unlock stops working. I'm unable to bind the key at all when in FIPS mode, so I disabled FIPS to bind the key and rebooted (which allowed auto-unlock to work), then re-enabled FIPS mode and it stopped auto-unlocking.

More info in my askubuntu forum post.

I'm hoping someone here might understand what's going on better than I do and can point me in the right direction.

Thanks!
