Few days ago I decided to upgrade to 8.2-STABLE, partially due to some long-standing Netgraph issues (which I discussed on freebsd-net). To my surprise, sio0 (well, now uart0) had become detectable even in spite of enabled SOL: uart0: <16550 or compatible> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0 uart0: [FILTER] uart0: console (9600,n,8,1) uart1: <16550 or compatible> port 0x2f8-0x2ff irq 3 on acpi0 uart1: [FILTER] Eventually I'm able to use comconsole in loader.conf and getty simultaneously. BTW. I looked at the BIOS setup on my box - it has "Legacy OS" knob, allowing to hide serial port occupied by SOL from non ACPI aware OS. It was disabled for all the time, so my problem was probably related to sio(4) and fixed in uart(4). -- * Fido: 2:480/124 ** WWW: http://www.frasunek.com ** NICHDL: PMF9-RIPE * * Jabber ID: venglin@nette.pl ** PGP ID: 2578FCAD ** HAM-RADIO: SQ5JIV *
