http://bugzilla.opensuse.org/show_bug.cgi?id=1159882 http://bugzilla.opensuse.org/show_bug.cgi?id=1159882#c38 --- Comment #38 from Robert Delahunt <radelahunt(a)gmail.com> --- I will install the kernel in the repository in the link. Please reply soon with what specific packages I need to install from it, and/or any other information, as I have only ever ran a different kernel than stock twice. "Back in my day" I would compile a static kernel for Slackware-Current. Now, however, I will need a slight bit of coaching. If this needs to come over direct email or text or whatever, please let me know. I will boot back into OpenSUSE LEAP 15.2 and await your instructions while adding the repo. -- You are receiving this mail because: You are the assignee for the bug.

https://bugzilla.suse.com/show_bug.cgi?id=1159882 https://bugzilla.suse.com/show_bug.cgi?id=1159882#c37 --- Comment #37 from Michal Hocko <mhocko(a)suse.com> --- (In reply to Robert Delahunt from comment #36) > http://www.puresimplicity.net/~delahunt/vmstat/cgroup_disable/ Thanks. The data seem to be in line with what we have seen previously: vmstat.1600781117 1600781118 [diff] nr_active_anon 166943 -3026 nr_active_file 85576 3 nr_inactive_anon 33207 8180 nr_inactive_file 3540169 9504 nr_dirty 667650 -203 workingset_activate 154 0 workingset_refault 2455 1 workingset_restore 0 0 pswpin 0 0 pswpout 2448 3118 The inactive list is really large and mostly clean so there shouldn't be any reason to swap out. I suspect the reclaim is confused for some reason. Again anonymous inactive list is low and needs rotation but I fail to see any reason why it should get reclaimed. get_scan_count should opt for page cache reclaim only. Could you give the newer kernel a try as noted in previous comment, please? -- You are receiving this mail because: You are the assignee for the bug.

[kernel-bugs] [Bug 1176741] Wifi with rtl8723de chipset not working

https://bugzilla.suse.com/show_bug.cgi?id=1176741 https://bugzilla.suse.com/show_bug.cgi?id=1176741#c2 --- Comment #2 from David Kerkhof <dutchkind(a)txoriaskea.org> --- Thanks for the reply. Although it's a bit disappointing since this chipset is already a few years on the market and I read somewhere that opensuse would backport drivers to it's kernel so I expected it to be supported in this version. Anyway, in the end I installed the latest stable kernel from download.opensuse.org and that one works and has secure boot support. thank you for your work -- You are receiving this mail because: You are the assignee for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=1159882 http://bugzilla.opensuse.org/show_bug.cgi?id=1159882#c36 --- Comment #36 from Robert Delahunt <radelahunt(a)gmail.com> --- http://www.puresimplicity.net/~delahunt/vmstat/cgroup_disable/ Here are some vmstats for the stock OpenSUSE LEAP 15.2 kernel. I started the dd command then realized I don't have a swap set, so I created one and added it. As soon as I ran swapon, it climbed to about 20MB or so. Still a bit better than the excessive swapping, but still, with 16GB of main RAM and nothing but Chrome running, that's excessive. Let me know if this is enough or you want me to install the latest kernel. I'm very eager to help. -- You are receiving this mail because: You are the assignee for the bug.

If this works around the problem then my theory about proportional reclaim distributed memory pressure to anonymous mostly cgroups would be a good fit. After that is confirmed then it would be great to run with the current kernel. Installing one from http://download.opensuse.org/repositories/Kernel:/stable/standard/ should do it. -- You are receiving this mail because: You are the assignee for the bug.
