Could you share the e820 map, reserve setup_data and TPMEventLog address with and without the patch?
All of these should be just be in the dmesg.

It's shared in the aforementioned bug [1] already.

6.11.2 dmesg (bad run):
https://bugzilla.suse.com/attachment.cgi?id=877874

6.12-rc2 dmesg (good run):
https://bugzilla.suse.com/attachment.cgi?id=877887

FWIW from https://bugzilla.suse.com/attachment.cgi?id=878051:
good TPMEventLog=0x682aa018
bad  TPMEventLog=0x65a6b018
