When I enable the I-pipe tracer, the problem goes away, i.e., there is no MDIO timeout, and so the freeze is never executed, and so there is no frozen trace to examine. Does this behavior give you any ideas about what the cause might be?

You can try enabling the I-pipe tracer, and triggering a trace freeze when the MDIO timeout happen. The trace has to have sufficiently many points to see the last interrupt corresponding to MDIO (if MDIO is interrupt based). -- Gilles. _______________________________________________ Xenomai mailing list [email protected] http://www.xenomai.org/mailman/listinfo/xenomai
