Hello,
as described here
(https://bbs.archlinux.org/viewtopic.php?pid=1787759#p1787759
<https://bbs.archlinux.org/viewtopic.php?pid=1787759#p1787759>) the patches
for the Renesas host
controller (https://www.spinics.net/lists/linux-usb/msg169384.html
<https://www.spinics.net/lists/linux-usb/msg169384.html>)
didn't work for me:
I compiled the current kernel (4.16.11) with the three patches and a
cherry pick
(fa31b3cb2ae143aa6e26974fcbe75689da60bdbe), but my Renesas USB 3.0
express card didn't work. I tried it with no kernel parameters and with
either
kernel parameter intel_iommu=on or intel_iommu=igfx_off. But it didn't work.
When I use kernel 4.12.7 or kernel 4.12.8 with:
git checkout v4.12.8
git revert 0e1f0eaed6c20db41ff61e024b361ee3ec9d686c #revert the noted commit
git cherry-pick 854e55ad289ef8888e7991f0ada85d5846f5afb9 #cherry-pick a
commit needed to build with gcc 8
git cherry-pick ad343a98e74e85aa91d844310e797f96fee6983b
The express card only works, when I boot linux with the card inserted.
When I reinsert it while running, it does not work anymore.
Cheers
Marcus
