I currently am testing suspend/resume on my desktop system. I already kept it in suspend to ram state in 2 weeks, and now I resumed it, and screen didn't came back, I tried switching vts it did seem to help, but then everything hung.

I got this in logs:

Actually above warning is unrelated, at least I now get it on each resume, but system works.

Well, it's difficult to say what problem this is.

It may be the problem with shared interrupts coming in too early during resume that should be fixed in the mainline.

Yes, the NVidia driver is necessary for resume to work with the newer NVidia adapters. Unfortunately.

Well, it's difficult to say what problem this is.

I thought that warning that I have seen in the logs is the reason for this hang as it was vt related.
I have seen patches here that fix very related bug.
I continue this test by only using S2RAM on that system about 4~5 times a day.

Best regards,
Maxim Levitsky
