Thierry mentioned on IRC that he encountered the same issue. And I
encountered it also.
So... I'd rather not revert the fix, as it's quite a nasty one, and it
happens while console lock is held, so it looks like the machine just
froze. But I don't know how it could be improved with the current kernel.
We could make the logos non-initdata, but I don't much like that option.
Or we could perhaps implement some new way to catch the freeing of initdata.
Any other ideas?
