Please confirm that: 1. your kernel is built with CONFIG_MAGIC_SYSRQ 2. cat /proc/sys/kernel/sysrq returns '1' 3. the serial console port is being held open by some user program (eg, getty or init) If any of the three above are not true, then break doesn't work. -- Russell King (rmk@arm.linux.org.uk) The developer of ARM Linux http://www.arm.linux.org.uk/personal/aboutme.html - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
