Update: I found the following in my dmesg, think it points to an of-by-one error in the pfn selection: Feb 9 19:47:00 Cyrus kernel: [ 0.000000] Top of RAM: 0x200000000, Total RAM: 0x200000000 Feb 9 19:47:00 Cyrus kernel: [ 0.000000] Memory hole size: 0MB Feb 9 19:47:00 Cyrus kernel: [ 0.000000] Zone ranges: Feb 9 19:47:00 Cyrus kernel: [ 0.000000] DMA [mem 0x0000000000000000-0x000000007fffefff] Feb 9 19:47:00 Cyrus kernel: [ 0.000000] Normal [mem 0x000000007ffff000-0x00000001ffffffff] I had a quick look but couldn't see where though.
