First, please note that the documented behaviour (You press the key
combo 'ALT-SysRq-<command key>'.) still works.
The problem at hand is that not all keyboards can handle this many keys
pressed at once, and that there also are keyboards broken in other ways.
The work-around suggested in the documentation ([Y]ou might have better
luck with "press Alt", "press SysRq", "release Alt", "press <command
key>", release everything.) does not work with keyboards that sends the
make and break codes for SysRq immediately after another, and this was
the reason for changing the behaviour (for broken keyboards) in
2.6.18-rc1. The new behaviour works with every keyboard the people
involved in this discussion has heard of.
That the documentation wasn't updated with the new work-around key
combination for broken keyboards was a mistake.
