Public bug reported:

Binary package hint: linux-image-2.6.27-5-generic

This is Kubuntu Intrepid Beta with linux-image-2.6.27-5-generic version
2.6.27-5.8 on an i686 Dell notebook. I assume it might be a kernel
issue, but I'm not sure.

Steps to reproduce:
1. Ctrl+Alt+F2 to change to vt2
2. Log in
3. Alt+F7 to change to kdm
4. Press and hold shift key
5. Select "Restart X server" from kdm menu
6. Wait for X to restart, no need to wait for kdm
7. Release shift key
8. Ctrl+Alt+F2
9. Type some text

Actual result: Shift key seems to be stuck
- Letters in upper case by default. Lower case letters possible through caps 
lock.
- Shifted symbols also for digit and punctuation keys. No way to enter digits 
or unshifted punctuation marks.
- Alt+Fx or Ctrl+Alt+Fx won't work, so no way to switch vt any more.
- Pressing and releasing shift keys (both left and right) doesn't solve the 
issue.
- Entering the password to sudo might be impossible for passwords containing 
digits or similar, leaving the power button as the only possible way to shut 
down the system.

I encountered this issue in "real live" while investigating some other
bug rendering my KDE session unusable. I was restarting kde sessions and
X servers quite frequently on vt7, and typing commands on vt2 in
between. I guess the system might have switched to the login screen on
vt7 automatically while I was just holding shift to enter a command. I'm
not sure about the exact steps, so I'm happy I could provide the easier
steps above, even if they seem somewhat artificial.
