2.5 seconds.

You would think this - but there are test suites (such as FWTS) which check
hardware sleep residency; and this throws the numbers off.

If you look at how many quirks for BIOS/EC issues I've developed over the years
unfortunately the reality is that many OEMs don't test Linux.  The ones that do
find issues like this and fix them in their firmware.  They often have little,
or no quirks and things work out of the box.

> Perhaps AMD could really push for a certification program for the EC. 

I don't really know what a "certification program" would do that a simple
series of manual tests wouldn't do.  Adding a test case of "boot system on
battery", "suspend system", "plug in AC", "resume system", "check performance"
would catch this.

But anyway - that's a business discussion not a technical one.
