ok, fixed this one, it was the CURRENT_PTR optimization on UP that broke
if 4K stacks were enabled. (i disabled the optimization for now)
But interestingly, your .config unearthed 2 other serious bugs (!) as
well: the spin_unlock_irq() upon printk was incorrect for !PREEMPT_RT,
and there was an assert introduced by the get-rid-of-bitlocks ext3
patches which was invalid on UP && !PREEMPT_RT. We had these bugs for
quite some time.
I've released -rt21 with these fixes, does it work better for you?
