We added some trace event information, but from this gap point (6208.695948-> 6208.708726), it appears that the Cobalt kernel was frozen and no interrupt handling occurred.
include trace point events :
irq_vectors:call_function_entry
irq_vectors:call_function_exit
irq_vectors:call_function_single_entry
irq_vectors:call_function_single_exit
