Everything looks OK within SRM, but once the kernel takes over control it seems that interrupts get lost - characters are only send in blocks and received only if characters are send. This is a PC164 specific problem. A reboot from any shell does work fine as well as rebooting from DDB after a panic - at least for all panics I remember. Has anyone a idea what happens specially with serial interrupts if DDB gets invooked via break? -- B.Walter BWCT http://www.bwct.de ticso@bwct.de info@bwct.de
