> I would be happy to unconditionally turning hot-add on and SRU the udev rule back to Ubuntu 14.04. As I (and Kay) said, this is okay for an SRU, but unconditionally second-guessing/changing the kernel defaults is just wrong and inefficient too. For yakkety and onwards this *really* should be fixed in the kernel (preferrably upstream too), and that silly rule be dropped. ** Changed in: linux (Ubuntu) Status: Confirmed => Triaged -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1233466 Title: Hot-Add Memory failing for lack of udev rule Status in udev: Unknown Status in linux package in Ubuntu: Triaged Status in systemd package in Ubuntu: Fix Released Bug description: It appears that the Hot-Add mechanism is not working because of lack of a udev rule.

[Touch-packages] [Bug 1233466] Re: Hot-Add Memory failing for lack of udev rule
I fail to come up with a use-case that just wants to add CPU/RAM without onlining it sooner or later. For virtual environments, you add CPU/RAM to use it and therefore want to online it once it appears. In a cloud environment (like ProfitBricks), it makes no sense to add CPU/RAM without using it, because you have to pay for it. Hot-add is supposed to work on recent kernels (>= 3.10). Kernel 3.2 had an issue, but I can't remember if adding CPU/RAM or onlining it causes the issue.

[Touch-packages] [Bug 1233466] Re: Hot-Add Memory failing for lack of udev rule
Maintaining an ever-growing list of vendors is error-prone and TBH quite silly. Are there any CPUs where we *don't* want hot-add? If not, why can't the kernel just default to enabling this, instead of userspace unconditionally turning this on? But if hot-add is supposed to work everywhere, then for SRUs at least the udev rule could be simplified to drop the vendor check. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1233466 Title: Hot-Add Memory failing for lack of udev rule Status in linux package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Fix Released Bug description: It appears that the Hot-Add mechanism is not working because of lack of a udev rule.
