After applying the next patch (or the whole serie), I get the following messages
during initramfs drivers probe:

Clocksource tsc unstable (delta...)
no cont in shutdown!
floppy0: FDC access conflict!

Then kernel boot stalls. I'll try gdbing into kernel but this may
require lots of efforts.
I don't quite understand how do these two patches influence FDC emulation, but
they do. Tell me if you need any additional info.
