Public bug reported:
Many times (around ~60% of them), resuming my laptop from suspend
results in a not-working keyboard.
Solution/Workaround is: close lid, let it suspend again, and try to
resume until keyboard gets working again.
Another solution is: plug an usb keyboard, and run something like "modprobe
usbhid" or "modprobe hid", and this unblocks also the laptop keyboard.
Probably this is a bug in the kernel, but I have not enough knowledge to
understand where it is located (maybe we can add some systemd hooks in
/lib/systemd to catch such events and reload the kernel modules?)
