[Bug 1661741] Re: [Dell Inc. Latitude E5470] suspend/resume failure
Which version of Ubuntu are you using? Did you try the magical incantation I listed in my initial post? I am currently using 16.04. There was a few days (maybe 2 or 3 weeks ago) when the problem reappeared but it disappeared again. I thought it might have been related to a new kernel version but I didn't get a chance to try the newest mainline kernel before it went away. If my instructions don't help, I'd suggest trying the newest kernel to see if that helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1661741 Title: [Dell Inc.

[Bug 1661741] Re: [Dell Inc. Latitude E5470] suspend/resume failure
So, I have a Dell Lattitude E7470 that had the very same problem. Running Linux Mint 18.1 with kernel linux-image-4.4.0-78-generic and BIOS 1.13.4 I installed kernel linux-image-4.11.0-041100-generic and still the problem is there. However, after I upgraded to BIOS 1.15.4, I can suspend well with 4.11 kernel but NOT with 4.4.0 (which works sometimes and sometimes it does not). Hope that helps. I ahve already suspended 5 times with the new BIOS and kernel 4.11 and all good. finger crossed. See we are talking about different models and BIOS, but Jonathan may be right that there is something nasty wrt BIOS. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1661741 Title: [Dell Inc.

[Bug 1661741] Re: [Dell Inc. Latitude E5470] suspend/resume failure
There are definitely at least *some* BIOS problems with the 5470. For example, it seems to have clock speed issues (where the CPU clock speed will stay between 400 MHz - 800 MHz) which I have to resolve using either `wrmsr -a 0x19a 0x0` or `cpupower frequency-set -g performance` or both. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1661741 Title: [Dell Inc.

[Bug 1661741] Re: [Dell Inc. Latitude E5470] suspend/resume failure
Ok, and like Jan, I managed to fixed things by one hibernation cycle with power plugged in, and one with no power connected. So it almost sounds like some weird bug in the laptop's acpi or bios or so, and I don't think this is an issues with Linux or Ubuntu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1661741 Title: [Dell Inc.

[Bug 1661741] Re: [Dell Inc. Latitude E5470] suspend/resume failure
Recently, my Dell E7470 started showing the same symptoms: resume works fine, but when waking from resume, it reboots instead of waking up. pm_trace show only a hah match on ACPI device 0d, quite like it does for the original reporter. The weird thing is, that all of this used to work fine. The problem started after I had hibernated and had the computer turned off for a few days. So it does seem there is some kind of link between hubernate and suspend issues here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1661741 Title: [Dell Inc.

Weird, right? I'm fairly content with my Dell but I think there are some Linux-related BIOS issues.

I have received brand new Dell Latitude E7470 with preinstalled Windows. I have reinstalled the system with Ubuntu 16.04.2 from flash, formatting the entire hard drive along the way. I have experienced the same problem. When suspended on power and waked up on power it worked. When I unplugged the power cable while suspended it rebooted. When suspended on battery it always rebooted. I have enabled hibernate as described above. Hibernated several times by different means (lid, menu button, shell command) in different states (powered, on battery, plugged and unplugged cable while hibernated) and suspend works now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1661741 Title: [Dell Inc.

[Bug 1661741] Re: [Dell Inc. Latitude E5470] suspend/resume failure
So, a strange thing happened. In order to mitigate the problem, I decided to switch to having the computer hibernate instead of suspend (I outline below the steps I did to do that). And then, on a whim, I tried suspending again. And it stopped crashing, even after I switched back to suspend completely. I didn't do any software updates or, as far as I know, anything else in the interim. So right now, I have my computer set to suspend and it seems to work fine. I was waiting a few days to see if the problem reemered but right now, I can't reproduce it at all. For your edification (and maybe for other people), here were the steps I followed: $ gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'hibernate' $ gsettings set org.gnome.settings-daemon.plugins.power \ lid-close-ac-action 'hibernate' \ && gsettings set org.gnome.settings-daemon.plugins.power \ lid-close-battery-action 'hibernate' - In /etc/systemd/logind.conf, make sure '#HandleLidSwitch=suspend' is commented out, and add HandleLidSwitch=hibernate - And then I saved the attached file to /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla To switch back, I reran the shell commands with 'suspend' instead of hibernate and then removed the changes to the config files. ** Attachment added: "com.ubuntu.enable-hibernate.pkla.disabled" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1661741/+attachment/4814420/+files/com.ubuntu.enable-hibernate.pkla.disabled -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1661741 Title: [Dell Inc.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.10 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
