You have the serial port disabled in the BIOS, or not set to the I/O port and IRQ that FreeBSD is expecting. Enable it in the BIOS and make sure the BIOS and FreeBSD agree about the settings by changing one or the other. I'm not sure exactly why this causes FreeBSD to freeze, but I have come across the problem as well. It is definately a hardware problem with an unfortunate software side-effect. -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet - Available for IA32 (Intel x86) and Alpha architectures - IA64, PowerPC, UltraSPARC, and ARM architectures under development - http://www.freebsd.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
