Bug Description
Binary package hint: kexec-tools
When kexec is intalled the default behaviour is to use kexec to perform fast reboots. However, when this is used the text VT consoles no longer show any output at all. They do show a cursor and indeed you are able to interact with the applications which are nominally on those VT's; for example it is possible to login and see the logins procesesses have been created.
The default should really not be to use kexec for reboots as this also prevents the user from seeing the boot menu and thus from choosing their next kernel. That side of the bug is already reported under bug #251242.

Note that I have tried this with a range of older kernels while trying to isolate the cause of the loss of text VTs and so can say if it is a kernel issue then it is systemic across a range of kernels; which is entirly likely. It is possible we should be turning off usplash before firing the kexec.
The simple work around is to disable kexec reboot. Which can be done by editing the LOAD_KEXEC entry in /etc/default/kexec configuration file.
