I did all these things in a alt-f2 console (no Gnome). And they still
did not work. I want some one to tell me they hit: cntl+alr+sysrq b and
got a reboot.
Running F17/x86_64, fully updated, XFCE/xwfm4 on my Dell N7110 laptop:
1. echo "1" >/proc/sys/kernel/sysrq
2. CTRL+ALT+F2 to get a text console
3. Logged in as root
4. LEFT-ALT+PRSCR+"b" = reboot
To reiterate, that was the left ALT key.
So it works for me, Aaron.
