Hi All, The first patch in this series is a fix for a suspend-to-idle issues introduced in 5.4 (see its changelog for details). The second one is more of an optimization, although some systems may need it too (depending on how fragile their platform firmware is). Kenneth, This series is roughly equivalent to the patch at https://lore.kernel.org/linux-pm/CAJZ5v0h1Ro75++4xuCznkx6GNYd+G5NpMGP96z1jdh=dm9uZbw@xxxxxxxxxxxxxx/T/#m11ca9a14efe4e5193bbda69767595a5fb7bd5479 The main difference is that it flushes system_wq before ec_query_wq, but that should not really matter if the issue you saw in 5.4 is the one described in the changelog of patch [1/2]. Please test this series and let me know if it works for you too. In case it does work, it would be good to know if patch [1/2] is sufficient to fix the suspend problem at least with ec_no_wakeup == 0 (it may not be sufficient with ec_no_wakeup == 1). Thanks!
