+QLINK is the RF front-end interface. Why it hangs is **not established**. The
+machine has a SIM slot and its modem worked under Windows, so the radio hardware
+is present and functional — this is not a WiFi-only SKU. Candidates worth
+investigating: a version mismatch between these images and what the device's
+TrustZone or boot chain expects, missing calibration data the modem cannot
+reach, or a kernel-side gap. It restarts about every 42 seconds until stopped.
+
+Note the same cabinets supply the GPU, DSP and venus firmware, all of which
+work. Whatever is wrong is specific to the modem.
