The > combo patch below fixed the crash for me, does it work on your box too? That gives /home/lsrc/quilt/linux/arch/x86/kernel/setup_64.c: In function 'setup_arch': /home/lsrc/quilt/linux/arch/x86/kernel/setup_64.c:468: error: implicit declarati on of function 'map_vsyscall' But after I add a prototype to vsyscall.h it seems to work.
