Public bug reported:
I have a strange issue but I'm not the only one
(http://ubuntuforums.org/showthread.php?t=2280045).
My hardware is Lenovo t450s with intel Hd 5500. Suspend works fine
(Although I haven't tested a long sleep yet). Intel rapidstart is
disabled in BIOS. Hibernate saves to disk and resumes fine if I do the
wakeup within a few hours. Any long-term hibernates (12 hours) don't
resume. The splash screen shows up and then a blank screen and
unresponsive keyboard. I don't have a capslock key, so don't know if
that is flashing.
I have been on multiple kernels 3.16,3.18,3.19 and 4.0 now. All of them
have shown this problem. If there are any specific debugs that I could
gather to help narrow down the issue, I would appreciate the guidance.
Thanks!
