I have a Soltek MB with a Celeron CPU which I use for FreeBSD 7 testing. Recently I wanted to use the serial port to communicate with a gsm phone. To my suprise this did not work and odd errors were reported - like phone not connected when the phone could tell me there was a connection. [esbjerg@bishop]% uname -an FreeBSD bishop.xbsd.net 7.0-BETA2 FreeBSD 7.0-BETA2 #0: Sun Nov 4 15:17:28 CET 2007 root@bishop.xbsd.net:/usr/obj/usr/src/sys/GENERIC i386 I looked at the boot messages and saw: sio0: configured irq 4 not in bitmap of probed irqs 0 sio0: port may not be enabled sio0: configured irq 4 not in bitmap of probed irqs 0 sio0: port may not be enabled sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0 sio0: type 16550A sio0: [FILTER] sio1: configured irq 3 not in bitmap of probed irqs 0 sio1: port may not be enabled sio1: configured irq 3 not in bitmap of probed irqs 0 sio1: port may not be enabled sio1: <16550A-compatible COM port> port 0x2f8-0x2ff irq 3 on acpi0 sio1: type 16550A sio1: [FILTER] I google for a while but without much luck. I have checked the BIOS settings which are irq 4 and 3F8 for port 1 and irq 3 and 2F8 for port 2. This should be correct but still FreeBSD reports otherwise. I suspect this has something to do with acpi(?). Could anyone give me hints on how to debug and correct this problem? -- Sven Esbjerg
