Alison, Does Ryan have your 32-bit kernel image? I think kernel 32-bit doesn't support spin table. Please work with Ryan if your PSCI patch is required for the test.

I see a continuous reboot, where the kernel starts then immediately resets: -------------------------------------------------- Starting kernel ... resetting ... -------------------------------------------------- So I wouldn't want to see these patches merged.
