You wanted to say 3.17-rc5?

So is it bad to use 3.16.2 and 3.17-rc5 because every kernel installs his
firmware files to the same directory and overwrites the other one's?

The kernel installs the firmware with most of the filenames of r(v)+numbers in
/lib/firmware/radeon/ .

And the gentoo package "x11-drivers/radeon-ucode-20140823" installs the files
with the chip codenames and some numbered files which are not installed by the
kernel in the same dir.

So much from me now for more confusion.

You marked that bug as resolved/invalid.

Would you please tell me in detail, how you fixed this? I'd like to reopen this
bug.
Reverting "drm/radeon/cik: Add support for new ucode format (v5)" did not help
me.

I know I have to bisect ... But this is new stuff for me.
