Mac UEFI boot 24x slower keyboard/touchpad troubled

[Richard]

When rebooting after a Linux session, the UEFI and grub boots are extremely slow and the process takes 3 minutes
- As soon as the kernel boots, ie. luks input, everything is fine again
- OS X boot and option-boot is slow too, fast after FileVault password input
- Internal keyboard and touchpad is extremely slow, like 30 s per key press.
- Plug in usb keyboard and mouse: works fine, while the internals are still slow

After an OS X ession upgrading to 10.11.04, the boot got fast again
- After the net Linux session, back to slow

Impact: boot takes 3 minutes

get-around: lots of patience, possibly use of external usb keyboard

first discovered on 15.10, exists on 16.04

Some more silly info

each keypress takes 7 - 20 s from key down to effect
In the grub menu a grub second is 11 s wall time

Sometimes the external mouse is bad, too. As in nowhere to be found. Then there will be nothing but patience.

[Richard (ismail-a)]

When you reboot using
sudo reboot
- boot is fast!

When you reboot using 4-second power button press, because Ubuntu froze
- boot is slow!

So this depends on how the computer is shut down.

[Richard (ismail-a)]

When the external mouse is in a bad state on boot, it has no power

When in a bad state and you re-plug it while in the option-boot menu, it gets power (ie. the red LED is now on)
- but it does not start working

I have the same issue with kernel 4.11.1, very slow keypress on boot but if I reboot from the interface, it works as intended

[Kai-Heng Feng (kaihengfeng)]

Can you file an upstream bug at https://bugzilla.kernel.org?

[Kostas Chatzikokolakis (kostas-chatzi)]

I had almost the exact issue described in this bug (the only exception being that in my case the internal keyboard was slow no matter what), and it was completely fixed after the macOS 10.12.4 update.

[Kai-Heng Feng (kaihengfeng)]

@moimael, do you keep your macOS in the machine? Can you update macOS as Kostas suggested?
