In the early boot sequence, 2.6 kernel freezes just after showing 'arch_exit' on the screen, and 'Console: colour dummy device 80x25' on the serial console. Even if I put printk() right after local_irq_enable() in init/main.c, this debug print won't show up. So it seems something causes kernel hang while enabling MSR_EE bit, but I can't figure out how to detect... Does anyone have a clue?
Perhaps you have an irq that won't shut up? Or maybe a problem returning from an exception handler (I'm assuming you have your own head.S). -- Hollis Blanchard IBM Linux Technology Center ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
