Boot stalled with repeate= d SMMU faults, including FSR=3D0x402, SID=3D0x1000 and IOVA=3D0x86b020c0. I then tested Jens Glathe's non-PAS EL2 overlay [1]. Keeping the kernel, initramfs, boot arguments and SLBounce unchanged, removing the two top-level ADSP/CDSP iommus properties allowed Linux to reach userspace and initialize KVM. Subsequent one- and two-vCPU Linux guests passed CPU and timer checks and shut down cleanly across two cold boots. The host remained responsive, and post-test kernel-log searches found no "Unhandled context fault" messages. These were RAM-only tests, without GPU or remoteproc modules, so they validate boot and basic KVM operation rather than full desktop or DSP support.
