[Bug 1570820] Re: Suspend failure
@peterriesde My thoughts exactly. I want to avoid having to run an unofficial kernel. I mean, on one hand I'm glad that I was able to find a work around (other than switching to another distro, since from I tested 2 other 4.4 based distros that don't appear to have this problem), but I'd rather be using the official supported kernel for added stability and security. The latest official kernel that was pushed to proposed (4.4.0-22.38), which is based on 4.4.7, still has this same bug, even though the mainline 4.4.7 doesn't. However, it has another (unrelated) bug regarding the my AMD Radeon HD 8870M, which doesn't happen on the xenial-proposed build.

[Bug 1570820] Re: Suspend failure
Same effect here as you described (Samsung Ativbook 7 730U3E with Intel/ATI graphic). Xubuntu 15.10 with all the updates worked. After upgrading to 16.04 suspend stopped working. Due to some issues with systemd during the upgrade I did a fresh install of 16.04 Xubuntu but ran into the same suspend problem. I hope you can fix this in the official Kernel as I'd like to stick to the "original" an 16.04 is a LTS version.

The latest v4.6-rc4-wily kernel (http://kernel.ubuntu.com/~kernel- ppa/mainline/v4.6-rc4-wily/) fixed the issue for me.

I added the "kernel-fixed-upstream" because the bug is also fixed on the latest upstream kernel available at http://kernel.ubuntu.com/~kernel- ppa/mainline/, which is 4.6.0rc3 at this time. However, please note that the shutdown/reboot issues that I found on 4.4.7 (comment #5) are also present on this kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1570820 Title: Suspend failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1570820/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1570820] Re: Suspend failure
-- PLEASE DISREGARD MY PREVIOUS COMMENT -- The suspend issue is not present on 4.4.6 mainline kernel. So this must be some issue with some additional patching that is done to the official kernel. Meanwhile, I also went back to the 4.4.5 kernel and it suspends and resumes flawlessly. Besides that, I noticed that 4.4.7 is not without its share of problems. First of all, it displays an error on boot stating that radeon VCE failed to initialize (I have a dedicate AMD GPU on my laptop, besides the Intel GPU bundled with the CPU). This is a minor thing (I guess). However, the more concerning issue I noticed is that resuming from a suspended state, I just can't shutdown or reboot the system. It freezes while shutting down on a black screen with a white blinking cursor. I waited for a while and nothing happened. This is probably unrelated with the rest of the bug. Notwithstanding, I thought that I should mention it just so that you are aware that 4.4.7 also introduces a few issues, even though it seems to be unaffected by the suspending issues that I've been facing on the official 4.4.0-18 kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1570820 Title: Suspend failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1570820/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1570820] Re: Suspend failure
So I just found this site "Ubuntu to Mainline kernel version mapping" that the official 4.4.0-18 kernel is based upon the updstream 4.4.6 kernel. So I just tried installing that version and suspend is broken. So this is something this must be something that was fixed upstream between 4.4.6 and 4.4.7. I'm not knowledgeable enough to go through all the commits between 4.4.6 and 4.4.7 and find out exactly which one fixed the bug so that you can create a patch for it. However, I did find out that the word "suspend" is mentioned a few times in the 4.4.7's changelog: https://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.4.7 So maybe someone else can pick up whatever is needed to fix the kernel suspend issues that I'm facing and import it as a patch to the official kernel. Or maybe you can rebase the oficial kernel to the 4.4.7 version after the oficial LTS release. I don't know if that's possible since I'm not aware of the kernel update policy. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1570820 Title: Suspend failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1570820/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
