I'm sorry for abandoning this bug report. It never got fixed in Kubuntu 10.04. We are currently using Kubuntu 12.04 with the 3.2.0-51-generic- pae #77-Ubuntu SMP kernel and REISUB works just fine. I didn't do all the testing with mainline builds because this is a production machine. My kernel version looks nothing like your example, so you might want to do the kernel-fixed-upstream tag. Feel free to close out the bug since it's working fine now, and let me know if there's anything else I should do before that happens.

Status in “linux” package in Ubuntu: Incomplete Bug description: My son uses Ubuntu 10.04 and I use Kubuntu 10.04. Both computers are desktop machines, and are not identical. On each of our systems, Alt+SysRq+REISUB fails to reboot our computers. STEPS TO REPRODUCE: 1) Close all open programs so that you're just on your Desktop. 2) Hold down the Alt and SysRq keys. 3) Slowly type REISUB. 4) Release the Alt and SysRq keys. EXPECTED RESULTS: Visual feedback when typing each letter of REISUB followed by the computer rebooting. (Note that I'm not sure whether there should be some sort of visual feedback when the letter R is pressed.) ACTUAL RESULTS: R does nothing. E says "Disconnected from Plymouth" and leaves the blinking cursor at a computer log-in in TTY 1. I kills a bunch of processes, disconnects the system BUS, and leaves me with a blinking cursor at a log-in prompt in TTY 1. S performs an emergency system sync and leaves me with a blinking cursor that is not at a log-in prompt in TTY 1. U Disconnects her from USB, does an emergency remount, and leaves me with a blinking cursor that is not at a log-in prompt in TTY 1. B does nothing. ADDITIONAL INFORMATION: Maco (one of your devs) tried it on an Ubuntu 10.04 machine and it successfully rebooted the computer. POSSIBLY RELATED INFORMATION: If, instead, we do Alt+SysRQ+REISUO to shut the machine down rather than reboot it, it successfully shuts the machine down: R does nothing.
