Description Woody Suwalski 2015-01-25 14:04:16 UTC 
Created attachment 112799 [details]
dmesg booted with drm.debug

The new MSI Hawaii board, used single or 2-headed.
The crash in 
[    5.654006] kernel BUG at drivers/gpu/drm/radeon/radeon_sa.c:321!
[    5.654008] invalid opcode: 0000 [#1] PREEMPT SMP 

The crash is 100% repeatable. The system will boot OK to X with radeon.modeset=0.
The kernel has added trace to verify the firmware requested.

Unclear about 64-bit behavior, since I am booting a live USB distro.
Distro based on Debian Jessie, with
X.Org X Server 1.16.2.901 (1.16.3 RC 1)
Release Date: 2014-12-09

possible fix

This patch will fix the crash you are seeing on 32 bit.  However it won't fix the fact the that acceleration does not seem to initialized properly.

dmesg with new crash on a patched kernel

With the patch, the original crash is not happening anymore.
However Radeon still crashes, now in radeon_driver_postclose_kms.

possible fix

This updated patch should take care of it.

Yet another radeon crash with the new patch

The new patch is causing black screen and no VTs.

One more try...

dmesg with the latest patch, system is functional now

With the V3 patch system boots and is functional.
A secondary problem could be investigated:
radeon 0000:01:00.0: disabling GPU acceleration

This problem was expected, and probably deserves a separate bug...
Comment 14 Woody Suwalski 2015-01-31 17:41:43 UTC 
The V3 patch permits to boot to X (albait with acceleration turned off)
Comment 15 Woody Suwalski 2015-02-11 00:30:56 UTC 
Fixed in kernel 3.19
