Installed that latest version, can confirm that apst is disabled without the max_latency setting kernel parameter ....
I have also found a new BIOS for the m/b: 0902 So will also try and installing that and revert back to one of the kernels with apst turned on, to see if any difference... or is it possible to turn the apst back on with a kernel parameter ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1705748 Title: Samsung SSD 960 EVO 500GB refused to change power state To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1705748/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
