But the USB issues seems separate from the graphics issues. My experience with suspend/resume on a TP X201 (Ironlake) with stable/9 (recent as of a couple of days) is as follows: With just the text console (no X), suspend/resume seems to work, except that the backlight does not come back on. (Have not tested Xorg with vesa driver.) With Intel/KMS graphics, suspend/resume partly works too. The backlight does come back on, but then the graphics wedges with a "GPU hung". Can provide logs of this. I will try head tomorrow to see if that makes any difference. Last time I did, there wasn't any. I have not noticed any USB issues, however, but will make some more tests.
