I've now basically emptied my /boot/device.hints file, so all the resources are properly recognized as "at acpi0" as they ought to be. (Btw., this even solves the problem where the fdc(4) KLD could not be successfully loaded except from the boot loader due to a resource allocation problem.) Anyway, how do I get my serial console back? sio0 no longer has the required flag 0x10, and my attempt to use hint.sio.0.at="acpi0" hint.sio.0.flags="0x30" as /boot/device.hints still doesn't change this as it appears to be ignored -- no flags are shown in the sio0 line in dmesg output: sio0 port 0x3f8-0x3ff irq 4 on acpi0 sio0: type 16550A So what's the trick to get a true serial console under full ACPI resouce control? (Once the kernel is booted, the getty starts OK on the port, but I'd like to have a true console.) Using -h in /boot.config, it's no problem whatsoever to operate the loader itself from the serial console. Only after the "boot" command, the system falls into silence until the getty's login prompt appears. -- cheers, J"org .-.-. --... ...-- -.. .
