Stefan reports that rebooting his ODROID-N2+ (using a G12B SoC) results in the board hanging. His kernel config uses: CONFIG_MESON_EE_PM_DOMAINS=y CONFIG_DRM_MESON=m He reports that his kernel config results in the DRM driver's .shutdown callback to be executed after the power domain driver's .shutdown callback. That's problematic because meson_ee_pwrc_shutdown disables the clock which are used by the VPU IP. This causes the board to hang.
I didn't dig deeply on this yet because this smells very much like an issue Art reported[1] and fixed. What kernel version are you using, and does it contain commit fa0c16caf3d7 (drm: meson_drv add shutdown function) Kevin [1] https://lore.kernel.org/dri-devel/20210302042202.3728113-1-art@khadas.com/ (local) _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
