I don't think so. 1 was the default value in 12.04 anyway.
In 12.10 with the value set to 1, I just confirmed that K, B and O all have the expected effect. E dropped me back to a tty, which I don't remember happening before but I could be wrong there. U seems to do what it's supposed to (lots of read-only filesystem errors until I rebooted). I didn't try I or S, and I don't think R ever did anything visible anyway.

I've tried using all means to edit /proc/sys/kernel/sysrq. gedit says it cant save as it cant create a backup ans save anyway doesn't work. Nano seems to work but on reboot it's back to 176.
How are you guys editing this file?
Writing to this pseudo-file is always overwritten by a reboot. The entire /proc directory tree is in the OS's imagination, they are not files on disk they are a view into the OS's inner workings.Code:sudo sh -c 'echo 1 > /proc/sys/kernel/sysrq'
As described by this post: http://ubuntuforums.org/showpost.php...38&postcount=6
You can set to reconfigure on reboot by editing /etc/sysctl.conf and adding the line:
Code:kernel.sysrq = 1
Doh, of course. Memory lapse. Cheers.
