dmesg - hang on resume
My laptop supports Intel Rapid Start Technology, which is a firmware feature
that makes the system suspend to disk after it has been in S3 for a while. As
far as I know, the OS is not aware of this and on resume it acts as if the
system had only been in S3.
This has worked flawlessly until recently. Starting from kernel v4.2 (I tested
rc1 and some previous snapshots) the system hangs on resume. There are no
issues if the laptop is simply suspended and the firmware doesn't make the
system suspend to disk.
Here attached there's the dmesg in which there's suggested to report the issue
here.
I used drm-intel-nightly (28217ad8476e98c106c3f78e06140b052e2b6b38) to get
these logs.
Just a note: things are worse compared to 4.2-rc1 since X becomes usable after
a while, while I had to switch to tty to get the logs with drm-intel-nightly.
Please, tell me if you need more information.</pre>
