So, checking /boot/device.hints shows: hint.uart.0.at="isa" hint.uart.0.port="0x3F8" hint.uart.0.flags="0x10" hint.uart.0.irq="4" hint.uart.1.at="isa" hint.uart.1.port="0x2F8" hint.uart.1.irq="3" > It may be possible that this file isn't being populated in your image, > or being read in by bhyveload. show from loader: OK show LINES=24 boot_serial=1 console=userboot currdev=disk0p3: interpret=OK kernelname=/boot/kernel/kernel loaddev=disk0p3: prompt=${interpret} smbios.bios.vendor=BHYVE Any ideas? Oh, I did verify that uart0 is functional by logging into the system and doing: echo foobar > /dev/cuau0 So, it's not like the console is not working, it's clearly a problem w/ the kernel deciding to use it as console.. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
