Actually I have already fixed that. The problem was in file 'op_helper.c' in implementation of 'eret' instruction: 'env->regs [15]=env->elr_el [1] & ~0x1;'. '1' need change to 'cur_el'. Also this bug has been fixed in latest qemu.

Thank you!

Don't do that, that code is an out of date development branch.
Use QEMU mainline 2.7.0 or better.

Then I'm afraid it's not really going to be possible to help
you much further :-(
