 We've found an initramfs that prevents the system from booting from the
 secure boot path (i.e. when it is read from a zip file). XO-1.75 running

 The system doesn't boot - it hangs with OFW still on screen. Serial shows
 the only kernel message:
 Warning: Neither atags nor dtb found

 Here is the failing initramfs:

 The system can boot from the same initramfs (unzip it...) with no

 I'm testing this against 13.1.0 build 2, but I guess pretty much any build
 will work. Put these 2 files in /bootpart/boot:
  * http://dev.laptop.org/~dsd/20120916/build2-failing/runos.zip
  * http://dev.laptop.org/~dsd/20120916/build2-failing/runrd.zip

 Now boot with:
 false to require-signatures?
 " \boot"   pn-buf place
 " int:" load-from-list drop

 If I repack the 12.1.0 released kernel/initramfs using the same method,
 the system boots OK.

  * http://dev.laptop.org/~dsd/20120916/12.1.0-working/runrd.zip

 I have verified that it doesn't matter which runos.zip is used - the
 problem is triggered when the new runrd.zip is put in place, and doesn't
 occur with the 12.1.0 released one.
