Comment 221 for bug 1791427

Somewhere in this long thread, I think, an engineer suggested the following.

Somehow, in my particular case - a case in which, on my ThinkPad X1CG6, no work-arounds worked and neither did the test version of the kernel patch - my motherboard was at fault.

Well, the engineer was right. For, I got my motherboard changed - for another reason - and 'deep sleep' now works properly.

Now, as it turns out - and the engineer who changed the motherboard did not tell me this - the new motherboard has a different model number to the old one. So either Lenovo has fixed the problem with a new version of the motherboard. Or else my old motherboard had an idiosyncratic fault.

By the way, did the kernel patch for the problem ever get merged?
