Add to the afflicted architecture list a ppc64 kernel running 32 bit
user space apps such as a dynamically linked busybox:

file bin/busybox

ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1 (SYSV),
dynamically linked (uses shared libs), stripped

All that is reported on boot is:

[clip]
VFS: Mounted root (nfs filesystem) readonly on device 0:13.
Freeing unused kernel memory: 264k freed
/sbin/init: error while loading shared libraries: out of memory: Cannot
allocate memory
Kernel panic - not syncing: Attempted to kill init!
Rebooting in 180 seconds..QEMU: Terminated

Reverting the patch solves the problem.

Jason.
