Strange... I have to send two breaks on hypervisor sun4v consoles. Because the way you send Alt-SYSRQ keycodes on serial consoles is BREAK+sysrq_code, and that's why two breaks are necessary to indicate a real break into the OBP prompt. I suspect it doesn't work for you in that other case because it's at a point before the serial driver has even registered yet. -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
