Michal,
commit 34b9c07a3 (microblaze: Disable stack protection from bootloader) results in the following qemu crash in 3.14-rc1.

I have seen this with qemu 1.6.0 and 1.7.0.
Reverting the patch solves the problem.
Is this a qemu bug, a bug in the code, or a bug in my configuration ? Any idea what I can do about it ?
Thanks, Guenter
