   It's a known problem. In case you hold the sysrq combination, all
key codes are passed to the sysrq code without any other processing until
a SysRq release code is seen to prevent sysrq commands from being passed to
apps. Anyway, this has the side-effect you describe, but as I still think
of sysrq as of a hacker-only tool and I don't know of any trivial way how
to fix it, I don't plan doing anything with it.

				Have a nice fortnight
