The following is an approximation of the boot messages that I see on the screen (the early ones are gone before I can eyeball them so this is a blend of a previous dmesg and what I see on the screen during a failure): [ 0.000000] Linux version 3.15.0-0001-gd37cf73 (swheeler@...ct) (gcc version 4.8.2 20131212 (Red Hat 4.8.2-7) (GCC) ) #52 Sun Jun 8 22:43:01 BST 2014 [ 0.000000] KERNEL supported cpus: [ 0.000000] Intel GenuineIntel [ 0.000000] Disabled fast string operations [ 0.000000] e820: BIOS-provided physical RAM map: [ 0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000009fbff] usable [ 0.000000] BIOS-e820: [mem 0x000000000009fc00-0x000000000009ffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000000e4000-0x00000000000fffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000000100000-0x000000003f77ffff] usable [ 0.000000] BIOS-e820: [mem 0x000000003f780000-0x000000003f78ffff] ACPI data [ 0.000000] BIOS-e820: [mem 0x000000003f790000-0x000000003f7cffff] ACPI NVS [ 0.000000] BIOS-e820: [mem 0x000000003f7d0000-0x000000003f7ddfff] reserved [ 0.000000] BIOS-e820: [mem 0x000000003f7e0000-0x000000003f7fffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fee00000-0x00000000fee00fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fff80000-0x00000000ffffffff] reserved [ 0.000000] bootconsole [earlyvga0] enabled [ 0.000000] Notice: NX (Execute Disable) protection cannot be enabled: non-PAE kernel!
