Hey hey, I updated yesterday, from some;thing like a 4.13 or 4.14 kernel to version 4.15.5 and couldn't use my PS/2 keyboard. I saw the LEDs flashing when the system started, but couldn't get any response from the keyboard upon login.
I've managed to get the system going with a USB keyboard.
My PS/2 keyboard is rather old. Is it more likely that the keyboard is broken, or is there a chance of a kernel configuration breaking usage of the PS/2 keyboard?
Does the keyboard function in BIOS? Does it work if boot another distro's live usb or cd? You said 4.13/4.14 before so I don't think you're affected by the initramfs changes in 2014: https://www.archlinux.org/news/linux-313-warning-ps2-keyboard-support-is-now...
