I also set the two variables in loader.conf. The result was that it loaded on boot, but for some reason it couldn't mount my root partition. I disabled acpi and was able to boot. I looked more carefully at the result of compiling, and this is what I saw: acpi.asl 123: If (S3EN) Error 1037 - ^ syntax error Here are the surrounding lines. To be honest, I really don't see what could be causing a syntax error. 118 Name (_S0, Package (0x02) 119 { 120 0x00, 121 0x00 122 }) 123 If (S3EN) 124 { 125 Name (_S3, Package (0x02) 126 { 127 0x05, 128 0x05 129 }) 130 } 131 Else 132 { 133 Name (_S1, Package (0x02) 134 { 135 0x01, 136 0x01 137 }) 138 } -Dan Name (OSFL, 0x03) Method (_INI, 0, NotSerialized) { If (MCTH (\_OS, "Microsoft Windows")) { Store (0x01, OSFL) } Else { Peter Schultz wrote: > Dan Hulme wrote: > >> Disabling ACPI fixes the problem.
