Hello again. I just realized that my first response to this thread two weeks ago was not actually starting from the end of the discussion. I hope I found it now... Must say sorry for this I am still figuring out how to follow these threads. I need to ask if we can either revert this patch or only modify the quirk to only run on the device in mention (ASMedia ASM2824). We have now identified it as causing devices to get stuck at Gen1 in multiple generations of our hardware & across product lines on ports were hot-plug is common. To be a little more specific it includes Intel root ports and Broadcomm PCIe switch ports and also Microchip PCIe switch ports. The most common place where we see our systems getting stuck at Gen1 is with device power cycling. If a device is powered on and then off quickly then the link will of course fail to train & the consequence here is that the port is forced to Gen1 forever. Does anybody know why the patch will only remove the forced Gen1 speed from the ASMedia device? - Matt
