Alt-SysRq reisub doesn't work?
I never managed to do it. I need to write the procedure in a paper stuck to the machine near the button :-p or I'll never remember how to do it. I think I tried once, did not work, years ago. Doesn't it have to be enabled?
Check: cat /proc/sys/kernel/sysrq *returns 0 if not enabled In openSUSE, probably returns 184 or similar, partially enabled, This does not allow control of keyboard, but it *does* allow sync, remount read-only, and signalling of processes (term, kill, oom-kill). However, it also *does not* allow reboot/poweroff (the "b" in "reisub"). To get full SysRq features, issue (as root): echo 1 > /proc/sys/kernel/sysrq I understand the reasoning to the default, but on a machine that I allow no physical access to anyone else, I set that to full features after I install openSUSE. Much more convenient and cleaner when it is required. -- -Gerry Makaro aka Fraser_Bell on the forums, IRC, and mail at openSUSE.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
