I'll have a look at this some time tomorrow. Confirmed, this is triggered by CONFIG_SMP which enables code expecting the tick device to be enabled, although it could not be enabled. Uniprocessor boots fine with the patch fixing the spurious call to __request_percpu_irq applied. With CONFIG_SMP, the core dereferences NULL in pipeline_set_timer_shot() likely at the first host tick the in-band code attempts to program. -- Philippe. ^ permalink raw reply [flat|nested] 10+ messages in thread
