I added the "proposed" source and from there installed kernel 3.19.0-46 (using Synaptic). Booted with acpi_force_32bit_fadt_addr and system froze. I get the feeling this kernel wasn't the one I was supposed to be testing with. Could it be because I am on Trusty? Is the proposed kernel released to

For reference: http://www.uefi.org/sites/default/files/resources/ACPI_6.0.pdf, section 5.2.9 Fixed ACPI Description Table (FADT), see the 32 bit PM registers (PM1a_EVT_BLK etc) and their 64 bit counterparts (X_PM1a_EVT_BLK etc). You can check if these are sane by running "sudo fwts acpidump - >

So it's highly likely that the 64 bit addresses used for specific PM registers are wrong in the FADT, where as they are correct in the 32 bit addresses. The FADT supports old 32 bit legacy addressing for PM registers and 64 bit addressing too. Unfortunately sometimes the firmware sets the 64 bit
