It's up and working for u-boot and loader, but once the kernel comes up the serial console falls silent. First noticed about two weeks ago. Backing down to an old kernel doesn't seem to help, as if something changed in userland. It appears that my userland was corrupted by a USB flash during make installworld, so lots of other things aren't working also... For now I'm trying to dig myself out of that hole. IIRC nothing special was needed to turn on the serial console, if that's changed please clue me in. On the plus side, single user mode now works with the USB keyboard, which is a great help. Thanks for reading, bob prohaska
