Hi, all, I did some S3 tests on an eeepc901, the total suspend time(from issue the suspend command to power down) is about 2.5s~3s. something interesting is that kernel runs disk sync before entering S3 state, and this takes about 0.7~1.2s. my question is that, why do we need this for s2ram? can we remove this and run sys_sync for S4 only? thanks, rui _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
