I don't think this is related to the original report since it's a different chip, but it would be nice if both you and Mike could bisect.

Btw, reverting the second patch was not so easy.

radeon_ring.c was splitted up and the patch had to be applied to radeon_ib.c .

the first patch has been reverted here: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/driver...

For me patch https://bugs.freedesktop.org/attachment.cgi?id=105904 does not help. But I think r600.c is not used for my chip. It is r100_ring_test that fails. I'm a bit confused, which files are related to my RS740 [Radeon 2100] (onboard graphic from 740G chipset)

I have to find out, how I can debug that failing ring test and to see, why it fails.

That's the issue - it seems there was an issue with the firmwares I downloaded

Isn't there new checking in the code to make sure the firmwares are correct?

Now running 3.16-rc5 with no issues

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.

The firmware is not shipped with the kernel. It's packaged separately. The firmware for your card has not changed in years so it's not likely to the same issue.

I downloaded the firmware files when they were first made available back when drm-next first added the support for the new firmware at the end of the 3.16 cycle

Those files must have been damaged - installing the latest linux-firmware (or radeon-ucode) fixed this for me

You are probably suffering from a different issue and should raise a separate bug
