Keyboard issues on a Thinkpad x200 with Libreboot

Description

Friday january the 20th I updated Trisquel and rebooted the system. Shortly afterwards the keyboard started to behave in a strange manner. Left shift key won't work, right shift key will work but with some letters it won't produce any result, capital or not... in order to start the system I need to introduce the password, and as a last resort I use Caps Lock as the last possible way to introduce a capital letter.

This does seem to me more a software problem than a hardware problem.

I have seen a similar behaviour once: the time I reflashed the BIOS with Libreboot *and* a GRUB password. That time I had to use Caps Lock too in order to introduce the password... until even Caps Lock stopped working. Then, I reflashed the BIOS with Libreboot without GRUB password, and everything was OK again.

Later on Sunday the problem seemed to vanish. Today, 46 hours after reporting the problem, everything is OK again. I updated Trisquel on Sunday, so I tend to think it was the update that provided the fix.
