Subject[PATCH 5/5] Always print panic message on current console
Date
The kernel offers with TIOCL_GETKMSGREDIRECT ioctl() the possibility to
redirect the kernel messages to a specific console.

However, since it's not possible to switch to the kernel message console after
a panic(), it would be nice if the kernel would print the panic message on the
current console.
