Hi
I'm running 4.16.8-1-ARCH and that controller does not work, whereas I remember it was working sometime before.
Now I'm travelling, don't have the controller with me, especially because it does not work anymore.
This is what a part of dmesg looked like in 4.16.8-1-ARCH:

For kernel 4.13.1-1-ARCH I have a similar output here, saved from the testing I did.
From the archlinux forum I got adviced to try older kernels, and to look for last the kernelversion in which
that controller still was working. That's why I was using the gcc8 in 4.12.y.
The patch you reverted to get things working does a pci reset function of the Renesas
xHCI controller in probe
8466489 xhci: Reset Renesas uPD72020x USB controller for 32-bit DMA issue
The message: "xhci_hcd 0000:05:00.0: xHCI host controller not responding, assume dead"
indicates that a 0xffffffff was read from the xHCI registers, so I'm guessing the
pci_reset_function_locked() didn't quite finish yet, or we don't get sane values from
the controller for some other reason..
There are others who have issues with this patch, I think Marc Zyngier has been looking
at some alternate approach

Hi,
I'm not used to writing bug-reports.
From: https://bbs.archlinux.org/viewtopic.php?id=236806, I got adviced to do that.
I have an usb 3 controller laptop expresscard
Renesas Technology Corp. uPD720202 USB 3.0 Host Controller (rev 02)
using that in a Lenovo X220 which does not work with the latest kernels.
In a Lenovo R400 it works.
After some testing, I came to the result, that
it was still working in kernel 4.12.7, and stopped working in kernel 4.12.8.
And with some advice and further testing it produces the same (working) results in
kernel 4.12.8 with 0e1f0eaed6c20db41ff61e024b361ee3ec9d686c reverted.
(
git checkout v4.12.8

There is a post from someone else regarding this controller at:
https://unix.stackexchange.com/questions/440741/install-usb-3-0-express-card-under-linux-arch-linux-tried-adding-kernel-param
who made a bug report here:
https://bugzilla.kernel.org/show_bug.cgi?id=199627
I don't understand, the 4.12.y kernel tree is long end-of-life, why are
you using that one? Does 4.16 work? 4.14.y?
Why are you using gcc8 on 4.12.y anyway, that is not going to work for
you very well, it barely, if at all, works on Linus's latest tree.
thanks,
greg k-h
