already tried fetching from http://people.freedesktop.org/~agd5f/radeon_ucode/
directly as well as installing standard Debian distri kernel & firmware
package, same error, not sure though if the numbers in the error were absolute
identical
- was some time ago, 3D accel isn't _that_ important as long as everything else
works fine, now finally got around to writing a bugreport

Sounds like there's a problem with your initrd or kernel if you built the ucode
into the kernel.  This is an issue on your end.

considering the age of that code I share your suspicions, but why then does a
stock debian kernel & initrd show same behavior as my self-compiled (newer)
one?

Looks like these all have the correct length. Are there files of the same names
somewhere else on your system that might get picked up instead? If not, it
looks like a bug in either the initrd generation or request_firmware().

"locate CEDAR_" shows only these 3 files, so there should be no other
duplicates with the same names on my filesystem...
as a stock Debian kernel/initrd is showing same behavior and my own
selfcompiled kernel does not use an initrd, the initrd related tools cannot be
the cause.
that leaves the pretty unlikely bug in the loader and/or some weird local
hardware problem - no idea how much different the cards in the cedar family
really are from each other?

Boot with "radeon.modeset=0 3"

as root:
rmmod radeon
modprobe radeon modeset=1

If it works it means debian initrd doesn't include the firmware. Your own
compiled kernel can't load the firmware because the radeon kernel module load
before your filesystem is accessible. ie you need to build the firmware inside
your kernel image.

There 99% chance that this issue is on your side. I tested cedar, lastest
kernel on a fedora and it doesn't have issue to load the firmware (firmware are
in the inirtd file)

It's got nothing to do with the hardware. request_firmware() reports sizes of
the files in question which do not match the sizes of the files on your system
(which match the expected sizes). So something goes wrong between your
filesystem and request_firmware(). The most likely explanation seeming a
problem when copying the files into the initrd, or maybe
/lib/udev/firmware.agent in the initrd doing something wrong or something like
that.

What does

 gunzip -c /boot/initrd.img-$(uname -r) | cpio -tv | grep CEDAR

say?

The '3' won't have any visible effect on a Debian system, you'd need 'single'
for single user mode.

> If it works it means debian initrd doesn't include the firmware.

It does include something (otherwise the failure would be different), but
possibly not the correct files.

stupid me should've checked this beforehand,
very sorry for having wasted your time & thanks for your patience...

...nope, as Debian considers that particular firmware to be "nonfree" it is not
included in the initrd at all, so it boils down to a somewhat misleading "bogus
length" instead of a more appropriate "file not found" error for all cases
above.

issue solved.

That the firmware is in the firmware-linux-nonfree package merely means it's
not installed on the system by default, it doesn't directly prevent the
firmware from getting included in the initrd.

The lengths in the original error messages are the amounts of firmware data
written by the /lib/udev/firmware.agent helper. If the firmware was missing
altogether, how could the helper guess their sizes?

Anyway, glad it's working for you now.
