Hello, I'm struggling with enabling serial console on Intel SR1630GP server platform and FreeBSD 7.4. In default configuration, my serial ports are detected correctly: sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0 sio0: type 16550A sio0: [FILTER] sio1: <16550A-compatible COM port> port 0x2f8-0x2ff irq 3 on acpi0 sio1: type 16550A sio1: [FILTER] Both serial ports are usable - sio0 is redirected to BMC and sio1 is a physical port. I can use getty on both ports. If I put following statements in /boot/loader.conf: boot_multicons="YES" boot_serial="YES" console="comconsole,vidconsole" I have correct output on serial console from loader and booting kernel, however after kernel is booted, the port is missing. Dmesg shows, that only one port is being detected, which formerly was sio1: sio0: <16550A-compatible COM port> port 0x2f8-0x2ff irq 3 flags 0x10 on acpi0 sio0: type 16550A, console sio0: [FILTER] Thus, I'm unable to run getty. I belive that this issue might be related to ACPI, as similar problem was already reported in http://markmail.org/message/chu6ilwhsxtarkfm Is there any solution to this problem?
