Yes. Hitting enter just doesn't have an effect.

It's probably not related to the patches in particular, but may
be related to TTY in general. Typically, when there's no device
found during bus enumeration that matches the device used for the
system console, then init(8) will not have a device for its stdin,
stdout and stderr. This used to result in a panic, but this may
have changed with the dev_t refcounting. This should also have its
effect when booting multi-user BTW.

So, make sure you see the device used for the system console probed
and attached in the dmesg. That's about the best thing I can suggest
without having read your report.
