According to AHCI spec v1.3.1, "7.3 Native Hot Plug Support", once LPM is enabled the hotplug needs to be disabled.
So I agree with 2), I think we should write document and let users know how to change the LPM for hotplugging detection. For 3) I don't think we need to change the way it works, because there can be lots of corner cases to cover, and not all servers need AHCI hotplug feature. We just need a good documentation to instruct users how to disable it. 4) is kicking the can down the road, the same issue will re-appear once those servers get upgraded. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1971576 Title: SATA device hot plug regression on AMD EPYC (Asus) server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1971576/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
