Peter H pointed me in the right direction (I missed this section in UPDATING):
20140405:
The uart(4) driver has been changed with respect to its handling
of the low-level console. Previously the uart(4) driver prevented
any process from changing the baudrate or the CLOCAL and HUPCL
control flags. By removing the restrictions, operators can make
changes to the serial console port without having to reboot.
However, when getty(8) is started on the serial device that is
associated with the low-level console, a misconfigured terminal
line in /etc/ttys will now have a real impact.
Before upgrading the kernel, make sure that /etc/ttys has the
serial console device configured as 3wire without baudrate to
preserve the previous behaviour. E.g:
ttyu0 "/usr/libexec/getty 3wire" vt100 on secure
