SysRq key is broken
Last modified: 2007-04-18 12:42:39 EDT
Description of Problem:
After any usage of SysRq (Alt+PrtSc combination), *any* key press/release is
treated as Alt+PrtSc+?, i.e. prints a short help of SysRq commands. The
keyboard isn't usable anymore, i.e. it doesn't enter keystrokes and even doesn't
switch consoles. The only exception is SysRq itself -- those commands still
work, so that one has an ability to cleanly reboot the machine with Alt+PrtSc+S,U,B.
Version-Release number of selected component (if applicable):
Steps to Reproduce:

machine ("echo 1 >/proc/sys/kernel/sysrq" should be enough, but I haven't
2. Press Alt+PrtSc+?
The short help message is printed and any other key begins to be interpreted as
The short help message is printed and nothing else should happen.
The machine has Asus P3B-F motherboard (100Mhz) and BTC 5126T PS/2 keyboard (but
this is probably irrelevant).
Arjan, shall I take it?
