--- Comment #10 from Niko Montonen <montonen.niko@gmail.com> ---
I have a Lenovo ThinkPad Edge E325 with the upgraded version of Tasev's APU,
the E450, with the HD6320 Wrestler graphics chipset, and I'm suffering from an
issue that would appear to be the same as this.

I'm currently running 3.14.1 on the machine, and it works just fine, but
3.15-rc1 and 3.15-rc3 both fail to resume from suspend (I haven't tested rc2).
The machine hangs completely (network interfaces do not resume etc.), so I'm
unable to get dmesg after suspend.

I feel it's worth noting that the machine also completely ignores the lid
closing with 3.15-rc3, and I believe there are lots of ACPI changes in 3.15,
which would explain a lot.

Are there notes somewhere on how to get some useful debug info for situations
like this?
