Public bug reported:

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.
