Hi, I am finally getting back to this project again and am now looking at a more recent version of RELENG_7 post the UART re-write. It now shows a bit of a different problem. I have a 5501 Soekris and if I boot with uart just in the kernel, all seems to work well. I updated the /boot/device.hints to reflect uart instead of sio and I can see the system console. However, if I have the 3com PCI modem installed, cuau0 becomes the modem and I am not able to login via the console 1 FreeBSD 2 FreeBSD Default: 1 /boot.config: -h FreeBSD/i386 boot Default: 0:ad(0,a)/boot/loader boot: Consoles: serial port BIOS drive C: is disk0 BIOS 639kB/261120kB available memory FreeBSD/i386 bootstrap loader, Revision 1.1 (mdtancsa_at_releng7.sentex.ca, Wed Jul 23 12:29:59 EDT 2008) Loading /boot/defaults/loader.conf /boot/kernel/kernel text=0x36ab14 data=0x325e0+0x2182c syms=[0x4+0x41890+0x4+0x544d6] | Hit [Enter] to boot immediately, or any other key for command prompt.
