Yes. I noticed that when I looked at your configuration. I have the same
card. And I think you are on the same bios too.

The only exception is the SSD. I'm still to find a reasonably priced SSD
in my locality.

PS: Like I've reported before, I have a pretty good suspend/resume rate.
I did dive deeper into what has been happening during suspend. The SATA
exceptions (I'm sure you must have seen that on your box) happen very
frequently during suspend image write (I use s2both). Also the intel
driver throws in many errors.

But after the fix (that was added in 3.19.3), the intel error is not
fatal anymore.


The errors I'm talking are (there may be more I've missed to scan and copy):

And I think the SATA errors and the relink to 3 Gbps is okay. The reason
being, afaik,  it is a rev 3 device connected to the rev 2 port. I still
need to open up my laptop and look into more specifics.
