SubjectRe: [patch] Real-Time Preemption, -RT-2.6.9-rc4-mm1-U8

you are getting them because interrupts get disabled somewhere in the
path. Do your changes perhaps introduce a local_irq_save() or
local_irq_disable()?

(in PREEMPT_REALTIME spin_lock_irq*() does not disable interrupts for
mutex-based spinlocks, so the only way to get irqs disabled is
explicitly.)
