http://bugzilla.opensuse.org/show_bug.cgi?id=1186944 http://bugzilla.opensuse.org/show_bug.cgi?id=1186944#c5 --- Comment #5 from Z Z --- I went through most of the previous kernel versions you suggested, going all the way back to 5.4 and all of them produce the same problems for me. The only one that doesn't seems to be the kernel available for Leap, as well as this custom Xanmod build that I found: https://build.opensuse.org/package/show/home:houge/Xanmod-openSUSE-TW Is it possible that kernel-vanilla is being compiled in an unusual way despite the goal of being the same as upstream? These problems never manifested when I was trying out Fedora, Ubuntu and as stated before, openSUSE Leap on the same hardware, so this is all very peculiar to me. I've been trying to search and see if there's some known issue with this specific hardware combination that other distros just patch for by default, but I've been coming up empty. -- You are receiving this mail because: You are the assignee for the bug.

Is it possible that kernel-vanilla is being compiled in an unusual way despite the goal of being the same as upstream?

Unlikely. It is the upstream code.

Well, a possible difference could be either other distros taking some downstream patches or having some different kconfig, or having some user-space setup that influence on the behavior...

Interesting. Thank you very much for the insight and all the suggestions, it's much appreciated! -- You are receiving this mail because: You are the assignee for the bug.
