Sorry, I take that back. I could have sworn it did resolve the issue,
but that does not seem to be the case.
This seems unrelated to powertop; `auto' seems to be the default setting
of /sys/bus/usb/devices/*/power/control, which is reset on reboot. In
any case, setting it to `on' does not solve my suspend issue.
It's not a hardware issue, because earlier kernel versions work just
fine.
I tried debugging this further, but even on a minimal Guix system, I
cannot seem to work around the problem.
Any advice, anyone?
