[Desktop-packages] [Bug 1528735] Re: Suspend reboots every second time on Lenovo G50-45
In a nutshell, it looks to me like this feature was broken somewhere between kernel releases 3.16 (working) and 3.19 (not working), POSSIBLY in combination with having a machine that has a BIOS version newer than mid-2015 when vendors updated their BIOS with the VU#976132 fix.

@VaclavSynacek, someone needs to change the subject of this bug or merge it into another/new one because it might get assumed that this problem is specific to a Lenovo G50-45 or even Lenovo devices in general, and hence not get the attention it deserves. I don't believe that it is specific to just Lenovo.

I also upgraded several times since my report on 2016-02-24. I am convinced the bug is a combination of 1) BIOS version (possible due to security fix of Vulnerability Note VU#976132 mentioned above) 2) Linux kernel in general (regardless of kernel version or distribution) 3) boot in UEFI mode Tests of various combinations of BIOS, distribution and kernel underneath. "Cannot suspend" means can suspend once, but freezes on second suspend and after hard restart prints "Warning!!! Boot script table modified" boot message and freezes.

OK, I just tested with a Live-USB disk of Linux Mint 17.2 Cinnamon (kernel 3.16) newly burned from the ISO file and suspend/resume works great. Multiple times in a row, from the shutdown icon, from the power button, and from the notebook lid close/open. So this is either Kernel or distro dependant and perhaps not related to the BIOS version as I thought. I tested this from a Live-USB of Linux Mint 18 Cinnamon (kernel 4.4) and it DOES NOT work, it has the same problem - first suspend/resume works fine, then upon second suspend it displays the yellow text warning and reboots the system at the BIOS level. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pm-utils in Ubuntu. https://bugs.launchpad.net/bugs/1528735 Title: Suspend reboots every second time on Lenovo G50-45 Status in pm-utils package in Ubuntu: Confirmed Bug description: Fresh install of Xubuntu 14.04.3, replacing existing OEM Windows 10.

[Desktop-packages] [Bug 1528735] Re: Suspend reboots every second time on Lenovo G50-45
I'm seeing this problem on various versions of Linux Mint from v17.3 Cinnamon with kernel 3.19 to v18 Mate with kernel 4.4 or 4.7. Apart from the OP problem description of symptoms with yellow text console warning message, I have suspicion that this problem is also causing the more severe problem with kernel 4.7 that even the first suspend/resume results in a system lockup/freeze upon attempting to resume. I think it may be important to first determine if this problem is specific to a machine and it's BIOS version. In this case I believe we are talking mostly, if not only, about Lenovo machines (like mine). I think it is possible this is a result of a BIOS update by Lenovo to fix a security hole described below. That said, my notebook's info is below. Note the BIOS version and date. Also note that the security hole (UEFI implementations do not properly secure the EFI S3 Resume Boot Path boot script) is not specific to Lenovo and MANY vendors would have had to make a similar patch - which might explain suspend/resume problems reported by various people with other notebook brands.

[Desktop-packages] [Bug 1528735] Re: Suspend reboots every second time on Lenovo G50-45
I have the same problem on Lenovo S435 and ubuntu-mate 15.10 on 4.2.0-30-generic x86_64 dual boot with Windows 8.1. But this problem started only after bios update from BBCN16WW(V1.03) to BBCN16WW(V1.07). With the previous bios V1.03 this never happened, even with the same kernel. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pm-utils in Ubuntu. https://bugs.launchpad.net/bugs/1528735 Title: Suspend reboots every second time on Lenovo G50-45 Status in pm-utils package in Ubuntu: New Bug description: Fresh install of Xubuntu 14.04.3, replacing existing OEM Windows 10.

[Desktop-packages] [Bug 1528735] Re: Suspend reboots every second time on Lenovo G50-45
Just updated to 4.2.0-27-generic #32~14.04.1-Ubuntu SMP, and this is still an issue. This may not actually be directly related to pm-suspend, but I put it here for lack of a better proximate cause. This may need to be transferred to be a kernel bug. I suspect it may be related to a reaction to http://www.intelsecurity.com/advanced-threat- research/content/WP_Intel_ATR_S3_ResBS_Vuln.pdf It can be reproduced by putting Ubuntu of just about any recent version onto a Lenovo G50-45, and suspending it twice. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pm-utils in Ubuntu. https://bugs.launchpad.net/bugs/1528735 Title: Suspend reboots every second time on Lenovo G50-45 Status in pm-utils package in Ubuntu: New Bug description: Fresh install of Xubuntu 14.04.3, replacing existing OEM Windows 10.
