IRQ 1/2[CPU#0]: BUG in __schedule at kernel/sched.c:3382 < ..... 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 ?
