Adds two troubleshooting entries to the README Q&A, from a first-gen XDNA1 (Phoenix) Linux bring-up:
ERT_CMD_STATE_ABORT/ mailbox timeout right after load — a stalenpu.sbinfrom a prior/distro install not matching the loadedamdxdna.ko. Documents that the plugin ships the matching firmware and that mixing sources is the common cause.EINVALwhile basic exec works — a distro in-treeamdxdnapredating ioctls the current XRT SHIM issues; points to the repo's stagingamdxdna.ko. (Related: Mainlineamdxdna(kernel ≤6.17) missing GET_ARRAY / AIE2 telemetry ioctls the current XRT SHIM expects #1447.)Both are real bring-up papercuts where the error message doesn't surface the version-mismatch cause. Docs-only; fits the existing Q&A format.
