PS/2 Keyboard stops working after soft reset

[Julian Lam]

Binary package hint: xorg

Running an old computer here, with a standard IBM KB-7353 PS/2 Keyboard. The keyboard input stops working after a soft reset (and only after a soft reset)! Hard resets configure the keyboard properly.

Problem also occurs on a different Compaq PS/2 keyboard. Have not tried using a USB keyboard, but I´d expect it to work properly.

I tried toggling numlock on and off during boot to see exactly when it stops working (as the keyboard works in the BIOS and during the GRUB bootloader), and the keyboard stops responding right after the xubuntu usplash pops up, and the OS starts loading.

Of note: Please note that XorgLog.txt shows the keyboard being set-up properly after a hard reset.

Also, XorgLogOld.txt refers to a bootup after a soft reset. Note that the keyboard setup is absent.

that's a kernel bug.
