How does this work? I've tried it but I didn't get this working at all. AFAIK, first step is to compile the CONFIG_MAGIC_SYSRQ into the kernel. Then, make sure there's a "1" in /proc/sys/kernel/sysrq; well it is. /usr/src/linux/Documentation/sysrq.txt says press "ALT-SysRq-<command key>", I've tried it out with SysRq=printScreen and cmd='h' for help, but nothing happens, even under normal conditions. What did I make wrong? Alex
