Hi, I wanted to bring to your attention the fact that the PS3 platform is broken on Linux 3.7.0.
i'm not able to boot Linux 3.7.0 on my PS3 slim. Linux 3.6.10 boots just fine but not 3.7.0 When i try to boot Linux 3.7.0 then my PS3 shuts down. So i cloned the Linux powerpc GIT repository and tried to find out which commits broke the PS3 platform. After some time I tracked it down to 2 commits: --------------------------------------------------------------------------------------------- commit 407821a34fce89b4f0b031dbab5cec7d059f46bc Author: Michael Ellerman <mich...@ellerman.id.au> Date: Fri Sep 7 15:31:44 2012 +0000 powerpc: Initialise paca.data_offset with poison It's possible for the cpu_possible_mask to change between the time we initialise the pacas and the time we setup per_cpu areas. Obviously impossible cpus shouldn't ever be running, but stranger things have happened. So be paranoid and initialise data_offset with a poison value in case we don't set it up later. Based on a patch from Anton Blanchard. Signed-off-by: Michael Ellerman <mich...@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <b...@kernel.crashing.org> ------------------------------------------------------------------------------------------------ commit 048ee0993ec8360abb0b51bdf8f8721e9ed62ec4 Author: Aneesh Kumar K.V <aneesh.ku...@linux.vnet.ibm.com> Date: Mon Sep 10 02:52:55 2012 +0000 powerpc/mm: Add 64TB support Increase max addressable range to 64TB. This is not tested on real hardware yet. Reviewed-by: Paul Mackerras <pau...@samba.org> Signed-off-by: Aneesh Kumar K.V <aneesh.ku...@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <b...@kernel.crashing.org> ---------------------------------------------------------------------------------------------------------- The first commit causes my PS3 to shut down. If i revert it then i'm able to boot Linux 3.7.0 and even see some boot messages on my screen. But then it hangs. The second commit is the reason for the hang as i figured it out. I reverted both commits in current Linux 3.7.0 and was able to boot Linux 3.7.0 on my PS3 slim successfully. Regards
