thanks for the report. Can you please provide a trace beside the dmesg
output? The following trace events should be enabled (via kernel command
line):

trace_event=timer:*,timer_migration:*,sched:sched_switch,sched:sched_wakeup,sched:sched_process_hang,irq:softirq_entry,irq:softirq_raise,irq:softirq_exit

Thanks,

	Anna-Maria
