Hi all,

I am in the process of upgrading an old server, a Proliant DL360 G7. The 
virtual serial port at uart1 worked with 13.2, but after 13.4 it only 
works until some point in the boot process, then its gone.

I just assume this is a change with acpi? but unfortunately I have no 
idea how to get the console back, sysctl only reports uart0 and so does 
dmesg.

loader.conf:
console="comconsole"
comconsole_speed=115200
comconsole_port="0x2F8"

Should device.hints read
hint.uart.1.at="isa"
hint.uart.1.irq="3"
hint.uart.1.port="0x2F8"

or
hint.uart.1.at="acpi"
hint.uart.1.port="0x2F8"

Ideas welcome... thanks!
