Yes, it does. Is there any estimates on when the patch will be merged into mainline? I want to put something into my distribution bug tracker, but it's unlikely they will use this patch before its stabilization. >As for your suspend problem did you pick up the new firmware that contained >the microcode update for Spectre? Or a microcode update from your >distribution? Yes, around a month ago (the firmware option). Still, there is a time frame between the firmware update and the problem surfacing. As I said it was eliminated by switching POST/fastboot to the thorough mode. I just have tried to reproduce the problem with previous settings, but with no success. So, that is (in a way) closed, but I have no idea what it was about. Thank you.
