@Nils, With the current default value, your NVMe will transit to PS4. So let's add kernel parameter 'nvme-core.nvme_core.default_ps_max_latency_us=2000' to test if PS3 also shares the same issue. If this issue persists, use 'nvme-core.nvme_core.default_ps_max_latency_us=0' to turn APST off.
@Ben, Is your laptop XPS 9550/Precision 5510, too? Please try 'nvme-core.nvme_core.default_ps_max_latency_us=5500', if the issue persists, please try 'nvme- core.nvme_core.default_ps_max_latency_us=200'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1678184 Title: APST quirk needed for Samsung 512GB NVMe drive To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678184/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
