I've narrowed it to the
down(&console_sem) in acquire_console_sem() in kernel/printk.c
called from con_init() in drivers/char/vt.c

I suspect the spin_lock_irqsave() in there hanging...

I have a lot of CONNFIG_DEBUG_ options activated, especially

So is there something I can do to narrow the problem.
How can I validate my irq setup ?
