I have also been testing this patch for a couple of days, and have not encountered any problems. I have now submitted a request for testing on the kernel bugzilla entry for the bug fixed by the earlier patch in question: https://bugzilla.kernel.org/show_bug.cgi?id=44161#c173 The CC list has 62 users, so hopefully we will get some more testers. The comment I posted is repeated below: -------------- Created attachment 131151 [details] process rather than discard events in acpi_ec_clear Hi all, If you have a machine that was (previously) affected by this bug, could you please take the time to try a new patch for this issue? A user with an older Samsung machine found that the earlier patch introduced some issues for them, so this is a new patch designed to be a better solution to the problem. Currently the new patch has only been tested on 2 affected machines (to my knowledge), so I would be very grateful if anyone else can test this patch (especially users with Samsung series 5 or 7 machines). You will need to use a recent kernel source like 3. (one which includes the earlier acpi_ec_clear patch), or otherwise apply the previous patch first: https://github.com/torvalds/linux/commit/ad332c8a45330d170bb38b95209de449b31cd1b4.patch Then apply the attachment ec_process_stale_events.patch Please test to see if your lid closing / suspending / etc. still work as intended with this patch. This new patch also provides some debug information after every resume/boot which will show up in dmesg something like: [ 1192.208056] ACPI : EC: acpi_ec_clear: EC_SC 0x28 [ 1192.217844] ACPI : EC: acpi_ec_clear: EC_SC 0x28 [ 1192.218844] ACPI : EC: acpi_ec_clear: EC_SC 0x28 [ 1192.222835] ACPI : EC: acpi_ec_clear: EC_SC 0x28 [ 1192.223834] ACPI : EC: acpi_ec_clear: EC_SC 0x28 [ 1192.224833] ACPI : EC: acpi_ec_clear: EC_SC 0x28 [ 1192.227833] ACPI : EC: acpi_ec_clear: EC_SC 0x28 [ 1192.228834] ACPI : EC: acpi_ec_clear: EC_SC 0x28 [ 1192.229832] ACPI : EC: acpi_ec_clear: EC_SC 0x28 [ 1192.230828] ACPI : EC: 8 stale EC events cleared Please report if you get any EC_SC bytes here _other than_ 0x28. I only get 0x28 on my machine but I am very interested to know if other affected machines produce something else. If you test it, please also report your system's product code, e.g.: # dmidecode -s system-product-name 900X3F # dmidecode -s baseboard-product-name NP900X3F-K01AU Many thanks, Kieran -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
