It is as the kernel said...

There is no *working* microcode update facility on that AMD CPU. I *think*
there is actually an extremely broken one that must not be used, but I could
be wrong about that, and it doesn't matter anyway.

No, there isn't, at least for operational system use. AMD never published
any microcode update data for family 0x0f, AFAIK.
I don't know about BIOS use (maybe the thing can be updated exactly once) or
the archive vaults of the AMD processor development labs :-)
