*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 21 kernel bugs. Fedora 21 has now been rebased to 3.19.5-200.fc21. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 22, and are still experiencing this issue, please change the version to Fedora 22. If you experience different issues, please open a new bug report for those.

I can't do the test because I no longer use that machine I managed to find out who owns the affected machine. I just wrote him to receive feedback about the bug and to provide new and useful data. Problem confirmed on Fedora 23 *********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 23 kernel bugs. Fedora 23 has now been rebased to 4.7.4-100.fc23. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 24 or 25, and are still experiencing this issue, please change the version to Fedora 24 or 25. If you experience different issues, please open a new bug report for those. *********** MASS BUG UPDATE ************** This bug is being closed with INSUFFICIENT_DATA as there has not been a response in 4 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously. Just asked the machine owner for feedback This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. I've submitted a patch with a quirk upstream for this. Given that there is little access to testing hardware for this, I'm going to close this with a resolution of upstream. The machine owner is available to test the patches. I only have to ping him using the "send email" button on fedoraonline.it because it is the only way to get him notified by a forum thread 1,5 years old. He seems to not have forum notifications enabled. He replied 6 days ago [1], I will ping him again [1]: http://forum.fedoraonline.it/viewtopic.php?pid=240226#p240226 Hi, (In reply to Germano Massullo from comment #14) > The machine owner is available to test the patches.

That is the option I went with for the quirk, as reading this bug-report as well as: https://bugs.launchpad.net/ubuntu/+source/linux-lts-trusty/+bug/1416940 That seems like the correct fix to me. Thank you. Regards, Hans (In reply to Hans de Goede from comment #15) > Ok, can you ask him to test a recent kernel with acpi_backlight=native > please ? I just finished testing with the machine owner and we *do* confirm that acpi_backlight=native fixes the problem :-))) Source http://forum.fedoraonline.it/viewtopic.php?pid=241017#p241017 So I've send a patch adding a DMI based quirk for this upstream, but unfortunately it turns out that it regresses some other dv6 models, it seems that the -6178sl part of the dv6-6178sl model does not show up in the dmi data, so we cannot distinguish between models with intel / ati / nvidia graphics based on dmi strings and my patch was breaking brightness control on other dv6 models. So I've send a revert of my patch adding a quirk for the dv6 upstream and dv6 users with the radeon model will have to keep using acpi_backlight=native as workaround I'm afraid. |
