As a short term fix we've reverted it there: https://crrev.com/c/5960799 ...apparently the patch is fine on newer kernels so maybe there is a missing dependency? Hopefully someone on this list can dig into this and either post the revert to stable 5.15 kernels or suggest additional backports. -Doug
