It was impossible to resist temptation to find where the story began. It
all started between 4.1 and 4.2-rc1. Bisecting points to this commit:
3d9fecf6bfb8b12bc2f9a4c7109895a2a2bb9436 is the first bad commit

x86/PCI: Use host bridge _CRS info on systems with >32 bit addressing
We enable _CRS on all systems from 2008 and later. On older systems, we
ignore _CRS and assume the whole physical address space (excluding RAM and
other devices) is available for PCI devices, but on systems that support
physical address spaces larger than 4GB, it's doubtful that the area above
4GB is really available for PCI.
After d56dbf5bab8c ("PCI: Allocate 64-bit BARs above 4G when possible"), we
try to use that space above 4GB *first*, so we're more likely to put a
device there.
On Juan's Toshiba Satellite Pro U200, BIOS left the graphics, sound, 1394,
and card reader devices unassigned (but only after Windows had been
booted). Only the sound device had a 64-bit BAR, so it was the only device
placed above 4GB, and hence the only device that didn't work.
Keep _CRS enabled even on pre-2008 systems if they support physical address
space larger than 4GB.
Fixes: d56dbf5bab8c ("PCI: Allocate 64-bit BARs above 4G when possible")

Title:
[nForce2] pata_amd pata_acpi can't load
Status in linux package in Ubuntu:
Triaged
Bug description:
The system is 15.04.
Since the 3.19.0-33-generic system fall to (initramfs) prompt. Now I
can boot the system only with 3.19.0-15-generic.
I always update the system and check new kernel packages, but they
have the same error.
In dmesg I found:
pata_amd 0000:00:09.0: can't enable device: BAR 0 [io 0x01f0-0x01f7] not
claimed
pata_amd: probe of 0000:00:09.0 failed with error -22
And analogical for pata_acpi.
P.S. I have a suspicion to the option CONFIG_PCI_BUS_ADDR_T_64BIT=y . But I'm
not linux kernel guru.
