Those more obviously include nsh functions. The trace in the dashboard does not and sees a GPF in propagate_entity_cfs_rq, which does not immediately appear related. That said, it is reported only once over a year ago, so probably still preferable to close. A new report will be opened if incorrect. ^ permalink raw reply [flat|nested] 3+ messages in thread
