Can you please take a look at this document: https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt and do some testing to see if it is a device driver issue? Thanks. I did some testing with s2ram and writing different test modes into /sys/power/pm_test. All worked just fine, including the "core" mode. I also tried the Suspend option in KDE Plasma Leave menu and after 5 seconds the laptop always woke up. But when I wrote "none" and tried with this one the bug could be reproduced and the laptop froze when it should wake up. Perhaps it has something to do with GPU, can you please add nomodeset to kernel cmdline and then boot into console mode and test again? I'm not sure if the screen can be turned on after resume, so please use ssh to login to see if the machine is back or dead. I added the nomodeset and booted into console mode and stopped X and then executed s2ram. The machine still freezes on wakup. Ping and ssh don't work, I also tried to press the CapsLock and it didn't switch the LED. Can I help with any other information? I don't have any idea what may be the cause. I think you can test some kernels to see if there is any working kernel Any update on the testing of other kernels? Is there a working one(hopefully)? Thanks for reminding me about this. I didn't try different kernels yet (except for a few versions starting with 3.14). I will try to test a few older versions during the weekend. ping I tried with about 10 kernels which were the latest in their version series (4.1.6, 4.0.9 ...) of kernels and no luck with any of them. Will continue with older versions next weekend when I will hopefully have more time. BTW, I suppose Windows works well here? And does the vendor provide any BIOS update on their website? Maybe that could help. Can you try acpi_sleep=nonvs boot parameter? |
