Yes, only for reboot/shutdown. The system does not do anythings wrong
even under high load. On reboot or hang those lines are never printed:

kernel: All buffers synced.
(it is from 10-stable sample, old -current samples are lost)
Moreover, GELI swap deactivation lines are never printed too (I already
mention that I change swap to normal, but nothing is changed).
I start to have raw guess that _any_ kernel printf in shutdown mode
cause not printf but premature reboot.
Finally I have good news and bad news with today's -current:
1) It seems your latest commit r316136 fix premature reboot issue.
Now I need to know how that helped. Do you used a non-default mode?
The change had 2 parts and I should have split it for testing. It
fixes the window sizing and constructors.
2) I still can't enter KDB using Ctrl-Alt-ESC, while booting, after
booting, after login and while shutdown - nothing happens.
boot -d enters KDB normally, but the keyboard sequence handler is
broken, not boot -d.
Try "<newline>~b". It is an old bug that Ctrl-Alt-ESC (and Ctrl-PrtScr)
are misconfigured by default. But I think the misconfiguration is the
same for vt. There are about 3 layers of options that have to be set
to "enable" or not set to "disable" to enable these keys.
