This turns out to be a long-standing bug in digi(4) that became fatal following phk's re-working of the TTY subsystem a few months ago. Basically digi(4) doesn't use ttymalloc(9) and its hand-crafted struct tty's are no longer good enough. There's a patch in kern/72436 and it would be nice if this could be applied before 5.3 goes out. (Does anyone else use DigiBoards?) Note that the patch won't apply to 6-CURRENT after phk's update a few days ago (which I wasn't aware of when I wrote the patch) - ttyalloc() doesn't exist in 5.x so merging fixes from 6 to 5 is going to be a PITA. >Problem 2: The system won't reboot.

Further datapoints: - The reboot after installing 5.3-BETA6 hung. - You can reboot from single-user mode but not from multi-user mode. - Enabling BROKEN_KEYBOARD_RESET has no effect. - It doesn't seem to be the Broadcom NICs. - The problem doesn't exist in 4.10 I've had a look at the PR database and haven't seen anything similar so one of us will submit a PR once we've done a bit more sleuthing. -- Peter Jeremy
