So far the only kernel tag with that fix is v4.11-rc1, I haven't seen it being
sent to stable trees.
Neither were there other platforms added - I see the G70 and S435 in the bug
here.
You might want to follow the kernel bug link and mention your platoform showing
the issue there as recommended by Carloslp in comment #23.
Adding a task for the kernel Team to consider a fix.

Title:
Suspend fails every second time on some laptops in UEFI mode
Status in kernel-package package in Ubuntu:
New
Status in linux package in Ubuntu:
Incomplete
Status in pm-utils package in Ubuntu:
Confirmed
Bug description:
Fresh install of Xubuntu 14.04.3, replacing existing OEM Windows 10.
Install detected UEFI, and installed in UEFI mode. (I have attempted
to change to legacy boot, and got it to a state where it was booting
without /sys/firmware/efi/ being present, but behaviour persisted.)
Suspending the laptop, whether by closing the lid, choosing the
suspend option from the menu, or directly typing "sudo pm-suspend"
works perfectly well... once.
The second attempt to suspend, whether immediately or hours later,
suspends the laptop (I can see the screen turn off, and hear the disk
and fans stop, but a moment later the screen shows bright yellow
console text declaring "Warning!!! Boot script table modified!!!
Please contact your vendor.", and then it hard reboots.
This appears to be a weird interaction between suspend and UEFI
protection, but others have reported that they have had working
suspend when installed alone (and presumably in legacy from the
start), but this behaviour appeared when reinstalled as dual-boot
(when presumably UEFI would have had to be on).
(http://askubuntu.com/questions/675683/suspend-does-not-work-more-
than-once-after-reboot-ubuntu-15-04-dual-boot/712232 and earlier
http://askubuntu.com/questions/651481/boot-script-table-modified-
please-contact-vendor, from different people.)
Beyond the investigations I have done, I know next to nothing about
UEFI, or how Suspend might be interacting with it. Much less why it
appears to work perfectly exactly once.
