It is quite possible to receive such an error message without there being any kind of "hardware problem" present. I get these routinely when I run my swampl.pl script and try to move the mouse around a lot while the machine is unresponsive. The swamp.pl script is designed to bring the machine to its knees under heavy paging and random file reads/writes. My take on this is simply that the machine is so damn bogged down that it doesn't get a chance to service the serial interrupts. Can you link the messages you get to some heavy job your machine does, or do you get them while it's chilling? If the former, don't worry about problematic hardware. If the latter, keep asking questions. :-) Ciao, Sheldon. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
