With these patches applied (actually a resync an hour
ago with the for-linus tree which includes them), the
freeze-during-boot-up problem that I have been seeing
with an old SATA boot disk (perhaps 1.5 Gbps) for
the last two weeks, has gone away.

That SATA disk is connected to the motherboard (Gigabyte
Z97M-D3H/Z97M-D3H, BIOS F5 05/30/2014) and has a standard
AHCI interface as far as I can tell. dmesg confirms that.
