Indeed: $ grep DSS .config # CONFIG_OMAP2_DSS is not set It's not enabled simply because it isn't enabled by omap3_defconfig. So maybe it should also be fixed for this ? I have zero knowledge of DSS, but shouldn't the kernel be able to suspend properly even if the DSS driver is disabled ? But maybe it's too complicated to have the DSS init sequence required to allow the system to hit RET outside the DSS driver. Thoughts ?
