[0] [Fix] The crash is attributable to the bus ID that the hibmc driver reports for the hibmc graphics card on the board. In particular, the bus id is missing the "pci:" prefix that most other cards provide: [1] - The busid reported on the arm64 system is "0007:a1:00.0" - The busid reported on a amd64 system is "pci:0000:00:02.0" X tests for this prefix. A missing prefix for PCI cards leads to an Xorg crash. Fix this by using the set_pci_busid function from the DRM core. [Testcase] Successfully tested on a D05 board. [2] [Regression Potential] Changes are limited to the hibmc driver, so any regression should also be limited to that driver. [Notes] I submitted the patch upstream. However, upstream is refactoring the drm core, and set_busid is going away. That does fix this issue but the regression potential of the refactor is enormous, so this seems like the wiser approach.
