When I run kokoro/test.sh -fvp at the tip of the master brach(as of today), I see the following failures when running the aarch64 tests. The test command line that fails is:

timeout --foreground 300s ./test/hftest/hftest.py --driver=fvp --out out/reference/aem_v8a_fvp_clang --out_initrd out/reference/aem_v8a_fvp_vm_clang --out_partitions out/reference/aem_v8a_fvp_vm_clang --log out/reference/kokoro_log hafnium --initrd test/vmapi/arch/aarch64/aarch64_test

Error log is:

ERROR: SMMUv3: Linear Stream Table cannot be supported when StreamID bits > 7

ERROR: SMMUv3: Failed to initialize driver

Panic: Could not initialize IOMMUs.

Has anybody seen this issue? I'll try to debug but thought I'll send an email in case somebody already knows the answer to this. Wondering if I'm missing a knob in the FVP.
