Hi all,
I applied last Ingo Molnar's realtime_preempt patch (-rt23) on a vanilla 2.6.16 kernel. My architecture is an ARM based CSB637 evaluation board from Cogent.
I obtain the following kernel oops :

< ..... Then kernel freezes .....>
This appears only when CONFIG_PREEMPT_HARDIRQS is enabled. The last trace is obtained using CONFIG_RT_PREEMPT which forces CONFIG_PREEMPT_HARDIRQS to "yes". For others configurations, when PREEMPT_HARDIRQS is disabled, it works great.
It seems to be something dealing with bad irq returns when hardirq serializing is enabled ?!?
Has anyone had ever seen this oops before ? Any clue to solve that ?
