In the above message, drm stands for Direct Rendering Management.
(Not what GNU/Linux types usually think about when DRM is mentioned.)
DRM is started during bootup at the point when the video framebuffer
device is set up. It sounds like a bug in the video driver.
Note that if you have a kernel boot parameter of the form "vga=...",
then the vesa framebuffer device is started very early during boot. It
is not until the xserver-xorg-video-<your video card's driver name>
framebuffer driver gets initialized that drm gets started.
If you installed the package xserver-xorg-video-vga and temporarily
disabled your regular video driver, and the above error did not occur,
that would pretty well nail down the source of the error.

Why didn't you install an AMD64 version of Debian?
