# EM160R-GL: no wakeup, no runtime PM.
# Why: with the lid closed on AC, the connected modem woke s2idle within
# ~1s every cycle (~1550 suspend/resume loops, 2026-09-21..22). Each resume
# re-probed MHI until the firmware hung (MMIO reads 0xffffffff, stuck in
# D3cold) and only a cold power-off recovered it.
