I got it! If I didn't mess it up but I don't think so.
Side question: do you have to do "fakeroot debian/rules clean" for every
step when bisecting? The guide was a bit unclear on that. I was just
thinking the compile process might be quicker if I didn't do clean in
between..

ACPICA: Tables: Enable default 64-bit FADT addresses favor
BugLink: http://bugs.launchpad.net/bugs/1479048
commit 0ea61381788a37d864f9841b0fe97d40f7058f3b upstream.
ACPICA commit 4da56eeae0749dfe8491285c1e1fad48f6efafd8
The following commit temporarily disables correct 64-bit FADT addresses
favor during the period the root cause of the bug is not fixed:
Commit: 85dbd5801f62b66e2aa7826aaefcaebead44c8a6
ACPICA: Tables: Restore old behavor to favor 32-bit FADT addresses.
With enough protections, this patch re-enables 64-bit FADT addresses by
default. If regressions are reported against such change, this patch should
be bisected and reverted.
Note that 64-bit FACS favor and 64-bit firmware waking vector favor are
excluded by this commit in order not to break OSPMs. Lv Zheng.

Title:
Updating 14.04.3 to latest updates renders system unbootable
Status in linux package in Ubuntu:
Confirmed
Bug description:
To reproduce (on this hardware)
1) Install 14.04.3 LTS (Ubuntu or XUbuntu)
2) Install updates
3) Reboot
The kernel used after update is 3.19.0-42. Booting with the kernel
that came with the install image (3.19.0-25) works fine.
This computer is a HP Compaq 6715s. I have looked at HPs support pages
for BIOS updates for this model but none was available.
