Hmm. Looks like a completely independent issue from the patch. Did you try booting that machine without the patch?

Ok, similar issue, I think - passing a non-1:1 address to __phys_addr().
But the call trace has nothing to do with gfs2 or the bitlocks:

I think this might be the
cont = __pa(container);
line in save_microcode_in_initrd_amd().
I see that Borislav is busy with some x86/microcode patches, I suspect he already hit this. Adding Borislav to the cc.
Can you re-try without the AMD microcode driver for now? This seems to be a separate issue from the gfs2 one.
