We need to limit rmo_top to 0x07c00000 on PS3. Sony's version of kexec-tools, at http://www.kernel.org/pub/linux/kernel/people/geoff/cell/ps3-linux-distro-kit-20061208/src/kexec-tools-1.101-4.src.rpm has the attached patch. (There are a couple of other alignment-related patches in there too), which may warrant investigation). Shouldn't the running kernel export this information directly, instead of making us guess? Surely _it_ knows?
Created attachment 151564 [details] Sony patch for rmo_top.
fixed in -66.fc7. Thanks! Since we've ripped out the platform determination code (since its not overly reliable), I'm just going to reduce the max rmo_top value to 0x7c000000UL for now. Being rawhide, If that has any adverse affects on anything else, we'll catch it early and be able to come up with something better.
