I volunteer for testing. The test device is
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] Turks PRO [Radeon HD 6570/7570/8550 / R5 230] (prog-if 00 [VGA
controller])
Subsystem: PC Partner Limited / Sapphire Technology Device e193
Flags: bus master, fast devsel, latency 0, IRQ 147
Memory at c0000000 (64-bit, prefetchable) [size=256M]
Memory at dfe20000 (64-bit, non-prefetchable) [size=128K]
I/O ports at e000 [size=256]
Expansion ROM at 000c0000 [disabled] [size=128K]
Capabilities: <access denied>
Kernel driver in use: radeon
Kernel modules: radeon, amdgpu
With the current patch, the driver crashes upon booting. Here is your

Building with W=1 also shows the following warnings:

drivers/gpu/drm/radeon/radeon_device.c:1280: warning: Excess function
parameter 'pdev' description in 'radeon_device_init'
I suggest to turn this patch into a little series. First do the trival
conversion from rdev->dev to rdev_to_drm() without any internal changes.
Then do the rest in a separate patch.

You still need to set dev->dev_private = rdev or the driver will crash.
I'd assume that this is the cause for the stack trace.
If you have an updated patchset, I can test again.
