Feedback Qubes-R4.0-rc4 on a Lenovo Thinkpad P71

[joeh...@gmail.com]

Before installing Qubes-R4.0-rc4-x86_64 on my laptop in UEFI mode but not secure boot, I first had to follow the instructions on
https://www.qubes-os.org/doc/thinkpad-troubleshooting/
summarized below:

<quote>In a nutshell, you need to use the Fedora livecd-tools to make a Qubes Installation USB Stick from the Qubes ISO image, then update the label on the partition of that USB stick to “BOOT”, and then update the BOOT/EFI/xen.cfg file on the USB stick so that all labels point to BOOT.</quote>

Then it installed properly.

However, there still seems to be some issues as reported by dmesg output below.
