Passphrase can only be entered after hitting ECO key

The machine is a Fujitsu Siemens S936 which apart from this issue works perfectly fine.
The issue I describe has been there forever (2+ years) but I finally got annoyed enough to ask for help.

I use full disk encryption using dm-crypt + LUKS so I have to enter a passphrase before Archlinux starts.
My mkinitcpio.conf has the following HOOKS:

HOOKS=(base udev keyboard keymap autodetect modconf block encrypt filesystems fsck)

When I am at the passphrase prompt, the keyboard does not work. Only if I hit the ECO key above the main keyboard, sometimes multiple times, I can enter my passphrase and have hitting the Enter key actually enter it.

Here is that key: https://www.notebookcheck.com/fileadmin … 1b7575.jpg

While this is of course in X and a much later stage I tried to find more info about the key via xev and evtest.
With evtest I found this key at /dev/input/event5, labelled as "Fujitsu FUJ02E3". Here is me pressing it once in evtest as root:

Monitoring with xev gives me this:

    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyRelease event, serial 38, synthetic NO, window 0x5400001,
    root 0x1bc, subw 0x0, time 1352628, (-299,203), root:(572,663),

    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

What could cause this? How can I fix this?

Re: Passphrase can only be entered after hitting ECO key

Thank you very much for posting this. I spent yesterday the whole day trying to figure out why I couldn't enter the password.

How on earth did you figure this out?

Re: Passphrase can only be entered after hitting ECO key

Confusion and anger mostly, and pure luck.

Could you share details about your setup as well? It would be great if we found out why this is happening and on which devices.

Re: Passphrase can only be entered after hitting ECO key

What kind of info can I share?

It's the same brand: a Fujitsu E754, i7, integrated Intel graphics.
