Warning: unable to open an initial console.

Hi,

I'm trying to write a console/tty driver, and I need help.  When the kernel
boots, I can see that console output is working through my driver.  However,
after the initial kernel boot, my console stops working.  Here are the relevant
parts of the boot log:

Using P4080DS HV machine description
Memory CAM mapping: 256/256 Mb, residual: 0Mb
Linux version 2.6.34-6506-00741-gbd4ea2b-dirty (b04825@efes) (gcc version 4.4.1

drivers/rtc/hctosys.c: unable to open rtc device (rtc0)
Warning: unable to open an initial console. -19
RAMDISK: gzip image found at block 0
VFS: Mounted root (ext2 filesystem) readonly on device 1:0.
Freeing unused kernel memory: 236k init

And this is where it stops.

As you can see, I have a console, and then I lose it.  What could cause this to
happen?

On the surface, it appears that init can't open /dev/console, but I can't figure
out what the root cause is.
