SubjectRe: [patch] Real-Time Preemption, -RT-2.6.10-rc1-mm3-V0.7.25-0

found the bug that i think caused the freezes and deadlocks reported by
Mark and Gunther. Here's the announcement of a debug feature:

> - debugging helper: the /proc/sys/kernel/debug_direct_keyboard flag
> (default: 0) will hack the keyboard IRQ into being direct. NOTE: the
> keyboard in this mode should only be used to access SysRq
> functionality that is not possible via the threaded keyboard handler.
> The direct keyboard IRQ can crash the system.

it turns out i accidentally left debug_direct_keyboard default-enabled
... no wonder it caused lockups!
