While I haven't seen the exact symptoms described here, I have seen some problems here in Chachapoyas. XO 1.5s running 11.3.1. It seems that machines that are running for quite some time with very active use eventually hang. I grabbed some longs from a Browse session, which seems to be the activity running when the crashes happen, but looking at the logs, it seems to be something failing at a lower level. See http://bugs.sugarlabs.org/ticket/3678 Also, at times, Restart fails to restart. -walter -- Walter Bender Sugar Labs http://www.sugarlabs.org _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
