I'm quite sure that one of the recent x86/kaslr changes causes this early 
x86-64 crash:

 BRK [0x179fb000, 0x179fbfff] PGTABLE
 BRK [0x179fc000, 0x179fcfff] PGTABLE
 BRK [0x179fd000, 0x179fdfff] PGTABLE
 PANIC: early exception 0e rip 10:ffffffff95203b9c error 0 cr2 ffffffff82a04a58
 CPU: 0 PID: 0 Comm: swapper Not tainted 3.12.0-rc5+ #229838
 Hardware name: System manufacturer System Product Name/A8N-E, BIOS ASUS 
 A8N-E ACPI BIOS Revision 1008 08/22/2005
 PANIC: early exception 0e rip 10:ffffffff95203e01 error 0 cr2 ffffffff82a04a58

Config and crashlog attached.

ffffffff95203b9c and ffffffff95203e01 is well outside the executable range 
is thus not in the vmlinux.

ffffffff82a04a58 is:

ffffffff82a03000 t init_per_cpu__gdt_page
ffffffff82bcd000 t _sinittext

Thanks,
