Spontaneous wake ups from suspend

When I upgraded my Ubuntu 14.04 to use kernel 4.0 (and now kernel 4.1) it apparently got a new feature: it would wake up from suspend in the middle of the day…

This bug provides a good read and has pointers to articles with more background. I’m seeing this on my Macbook Air and I am still not sure what the root cause is. I’m also not sure if it is “Intel Rapid Start Technology”, as Apples don’t have a BIOS to speak off.

During two Ubuntu 14.04 upgrades, both on a Mac (so needing an EFI boot), grub was borked after the install resulting in a grub rescue prompt when booting.

The actual error was error: symbol 'grub_term_highlight_color' not found.

Needless to say I couldn’t get the system to boot from this prompt.

I had a Fedora boot USB stick laying around, but using that did not really fix the problem, in any case I could use it to copy off /home if I could not rescue the system.
