[09:34] <mmantel> Hello guys, i have just one little question, from which kernel version ubuntu adds the CONFIG_HOTPLUG_CPU options ?
[09:44] <cjwatson> mmantel: (not a kernel developer, but) it goes back at least as far as 2.6.22-1.1 in Ubuntu 7.10, very probably earlier
[09:53] <mmantel> Hooo ok, i have a problem with a VM , doesn't have hotplug with a kernel 3.19. Maybe i have to enable something or pass a cpu option from my hypervisor ?
[10:23] <tomreyn> mmantel: there's no supported ubuntu release running this kernel version. the oldest supported kernel version (besides ESM) now is 4.4.0 (in Ubuntu 16.04 LTS)
[10:51] <apw> and even that is 3.13
[14:57] <LeoB> Hello there! Is there any backport happening for this patchsets on ubuntu kernel (18.04) ? https://patchwork.kernel.org/project/linux-mm/list/?q=mm%2C+thp%3A+consolidate+THP+gfp+handling+into+alloc_hugepage_direct_gfpmask 
[23:37] <snadge> i have managed to confirm my pc doesn't crash with the lowlatency kernel, if I use the 5.0.11 one from the mainline ppa
[23:38] <snadge> so im just going to do that.. im not sure how reporting a bug that my PC randomly crashes with zero diagnostic information and no ability to reliably trigger it.. ie.. it just happens randomly after 1 or 2 days, sometimes whilst idle, sometimes whilst im using it
