I do not think so, this really looks like SCTP specific
, we now have dozens of traces all sharing :

sctp_transport_route+0xad/0x450 net/sctp/transport.c:293
sctp_packet_config+0xb89/0xfd0 net/sctp/output.c:123
sctp_outq_flush+0x79c/0x4370 net/sctp/outqueue.c:894
sctp_outq_uncork+0x6a/0x80 net/sctp/outqueue.c:776
sctp_cmd_interpreter net/sctp/sm_sideeffect.c:1820 [inline]
sctp_side_effects net/sctp/sm_sideeffect.c:1220 [inline]
sctp_do_sm+0x596/0x7160 net/sctp/sm_sideeffect.c:1191
sctp_generate_heartbeat_event+0x218/0x450 net/sctp/sm_sideeffect.c:406
call_timer_fn+0x230/0x940 kernel/time/timer.c:1326


Some kind of infinite loop.

When the hrtimer fires, it can point to any code that sits below but does not necessarily have a bug.
