keyboard input is not working when mdadm is showing "degraded device" and system will boot after timeout to busybox

[Michael Basse]

I am using mdadm to manage a Raid10 volume. One disc is missing at the moment. When i start the system mdadm is telling me this and ask me if i want to boot the degraded raid anyway. The problem i am facing that the keyboard is not working there. its working in the grub-menu and iin the busybox but i cant press "y" to say "boot it anyway.

When i press "esc" the black TTY1 is switching to the violet TTY1 but in none of them the keyboard is working. Tried usb and ps2 keyboard.

i dont know if this is a bug in mdadm or in the general tty window. Attached you will find a picture with the issue (timed out)

Just for the info, i opened the bug with another system (where mdadm is not installed) because of that mdadm is shown as "not installed" in this report

[Michael Basse (michael-alpha-unix)]

the affected system is a normal ubuntu 12.04 amd64 server edition without a gui
