initramfs on arm64 (LSK) issues on fastmodels

Hi,

I am trying to use a basic initramfs containing a 32bit busybox when booting the LSK built for arm64 on the ARM FVP.

The initramfs I am using works fine on the arm32 kernel running on 32bit model.

It unpacks ok on the 64 bit model but in init/main.c it tries to run the /init script I get an ENOENT error returned from sys_access

ret = sys_access((const char __user *) ramdisk_execute_command, 0);

/init does exist in the initramfs...

Anyone got any ideas for what the problem is?
