[Bug 1375995] Re: [HP Compaq dc7800 Small Form Factor PC] suspend/resume failure


Did an upstream bug get filed for this? I have the same pc model (HP Compaq dc7800p) and have always seen the same odd behaviour where the pc must first be put into hibernate before it will be able to resume from suspend to RAM. I have seen this behaviour in both Ubuntu and Arch linux (every version I have tried going back several years).

I currently don't use Ubuntu on this pc and came across this report
looking for something else (updating kernel from 3.16.2 to 3.17.3 on
Arch also broke my ability to hibernate so I couldn't access suspend of
any kind without downgrading again). But I thought an additional
confirmation of this bug (and as an upstream issue) could be helpful.
