When the resulting kernel is booted the mmc device which contains the root file system is not available. Fix: add CONFIG_MAILBOX to qcom_defconfig Fixes: ab460a2e72da ("rpmsg: qcom_smd: Access APCS through mailbox framework" added a "depends on MAILBOX") Signed-off-by: Frank Rowand --- Bjorn suggested that multi_v7_defconfig might need this same fix but I don't have a target to test on so I have not included that change in this patch Tested on Qualcomm APQ8074 Dragonboard arch/arm/configs/qcom_defconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm/configs/qcom_defconfig b/arch/arm/configs/qcom_defconfig index 6aa7046fb91f..bd6440f23493 100644 --- a/arch/arm/configs/qcom_defconfig +++ b/arch/arm/configs/qcom_defconfig @@ -207,6 +207,7 @@ CONFIG_MSM_MMCC_8974=y CONFIG_MSM_IOMMU=y CONFIG_HWSPINLOCK=y CONFIG_HWSPINLOCK_QCOM=y +CONFIG_MAILBOX=y CONFIG_REMOTEPROC=y CONFIG_QCOM_ADSP_PIL=y CONFIG_QCOM_Q6V5_PIL=y -- Frank Rowand
