I suspect (but have no way to confirm) that happens because the sound
system is still connected to it. You could try to stop the sound
daemon. I think it's arts in kubuntu, so try

killall arts

or something to that effect.

If that doesn't work, reboot, choose the recovery mode in grub. Then
after its booted and you are logged in as root, try to take out the
card. Because it's not being talked to, that should be safe to do. If
that crashes the system, I'm out of ideas. If it does not crashes the
system, you know it's not a kernel bug, and you need to find the
service that talks to the device.

hope this gives you some ideas to try
