I tried reinstalling to the USB drive from the current snapshot. This
time it just hangs at "root device: ".  UEFI can find the USB3 stick
to boot from, but it cannot be found to mount it as root. I installed
again without using encryption and got the same result. It hangs at
"root device:  ".


When booting from USB2, I get the following dmesg:
