<HTML><BODY>Hi,<br><br>I wanted to bring to your attention the fact that the PS3 platform is broken on Linux 3.7.0.<br><br>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<br>When i try to boot Linux 3.7.0 then my PS3 shuts down.<br><br>So i cloned the Linux powerpc GIT repository and tried to find out which commits broke the PS3 platform.<br>After some time I tracked it down to 2 commits:<br><br>---------------------------------------------------------------------------------------------<br><br>commit 407821a34fce89b4f0b031dbab5cec7d059f46bc<br>Author: Michael Ellerman <michael@ellerman.id.au><br>Date: Fri Sep 7 15:31:44 2012 +0000<br><br> powerpc: Initialise paca.data_offset with poison<br> <br> It's possible for the cpu_possible_mask to change between the time we<br> initialise the pacas and the time we setup per_cpu areas.<br> <br> Obviously impossible cpus shouldn't ever be running, but stranger things<br> have happened. So be paranoid and initialise data_offset with a poison<br> value in case we don't set it up later.<br> <br> Based on a patch from Anton Blanchard.<br> <br> Signed-off-by: Michael Ellerman <michael@ellerman.id.au><br> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org><br><br><br>------------------------------------------------------------------------------------------------<br><br>commit 048ee0993ec8360abb0b51bdf8f8721e9ed62ec4<br>Author: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com><br>Date: Mon Sep 10 02:52:55 2012 +0000<br><br> powerpc/mm: Add 64TB support<br> <br> Increase max addressable range to 64TB.

If i revert it then i'm able to boot Linux 3.7.0 and even see some boot messages<br>on my screen. But then it hangs. The second commit is the reason for the hang as i figured it out.<br><br>I reverted both commits in current Linux 3.7.0 and was able to boot Linux 3.7.0 on my PS3 slim successfully.<br><br>Regards<br><br data-mce-bogus="1"></BODY></HTML>
