So, since ravb driver is probed within 4 seconds, we can use NFS rootfs cor= rectly. However, after these patches are applied, since the patches are always wait= ing for 30 seconds for of_iommu_configure() when IOMMU hardware is disabled, drivers/base/dd.c= output WARN. Also, since ravb cannot be probed for 30 seconds, we cannot use NFS rootfs = anymore. JFYI, I copied the kernel log to the end of this email. I guess the patches will be merged into v5.7-rc1 because the patches are co= ntained from next-20200316, I'd like to fix the issue in v5.7-rcN cycle somehow. [1] - R-Car H3 (r8a77951). - Using defconfig of arch/arm64. -- So, the IOMMU hardware of the environment is not enabled.
