I have reversed:

+reduce-tlb-flushing-during-process-migration-2.patch

and it cured this Oops, though it has nothing in common with the console,
obviously.

The serial console just does not work for me at all (earlyprintk apparently
does). Attached is what I get from the earlyprintk. Ther rest of kernel
messages goes to the local console (tty0), although it is not even present in
the kernel command line (sigh).
