On my Ivy Bridge i7 mobo w/ Radeon graphics, the 4.1-rc2 kernel oopses hard, requiring a hard reset:

The 4.1-rc1 and earlier kernels were fine.
git bisect identified the following as the first bad commit:
0f55db36d49d45b80eff0c0a2a498766016f458b is the first bad commit commit 0f55db36d49d45b80eff0c0a2a498766016f458b Author: Alex Deucher <alexander.deucher@amd.com> Date: Tue Apr 7 09:52:42 2015 -0400
drm/radeon: only mark audio as connected if the monitor supports it (v3) Otherwise the driver may try and send audio which may confuse the monitor. v2: set pin to NULL if no audio v3: avoid crash with analog encoders Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org

The graphics card is:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV370 [Radeon X300/X550/X1050 Series] 01:00.1 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] RV370 [Radeon X300/X550/X1050 Series] (Secondary)
and the monitor is some Dell 24" model w/o audio.
My .config has
CONFIG_DRM=m CONFIG_DRM_KMS_HELPER=m CONFIG_DRM_KMS_FB_HELPER=y CONFIG_DRM_RADEON=m # CONFIG_DRM_RADEON_USERPTR is not set # CONFIG_DRM_RADEON_UMS is not set # CONFIG_FB_RADEON is not set
(Full .config available upon request.)
