Just to rule out the aspect that your issue might be fixed by microcode
but that microcode needs to be loaded early, can you enable the early
microcode loader, put the microcode in initrd as described here:

Documentation/x86/early-microcode.txt

and retry?

I'm working on having it built-in too, in the case where people don't
use initrd, but that's 64-bit only for now.

Thanks.
