Смотрите, какая красота - очень низкоуровневый debug проблем с ACPI ноутбука от ASUS.
"Yet, the firmware ignores MUX state nudging the iGPU path (GFX0) and, worse, engaging dGPU cut/notify logic (PEGP/PEPD) every 30-60 seconds. The dGPU in mux mode isn't just "preferred" - it's the ONLY path to the display. There's no fallback, and no alternative. When the firmware arms DGCE (power off), it's attempting something architecturally impossible.
Most of the time, hardware sanity checks refuse these nonsensical commands, but even failed attempts introduce latency spikes causing audio dropouts, input lag, and accumulating performance degradation. Games freeze mid-session, videos buffer indefinitely, system responsiveness deteriorates until restart.
The Catastrophic Edge Case
Sometimes, under specific thermal conditions or race conditions, the power-down actually succeeds. When the firmware manages to power down the GPU that's driving the display, the sequence is predictable and catastrophic:
* Firmware OFF attempt - cuts the dgpu path via PEG1.DGCE
* Hardware complies - safety checks fail or timing aligns
* Display signal cuts - monitors go black
* User input triggers wake - mouse/keyboard activity
* Windows calls PowerOnMonitor() - attempt display recovery
* NVIDIA driver executes _PS0 - GPU power on command
* GPU enters impossible state - firmware insists OFF, Windows needs ON
* Driver thread blocks indefinitely - waiting for GPU response
* 30-second watchdog expires - Windows gives up
* System crashes with BSOD"
Кстати, удивлен, что под винду есть такие глубокие способы отладки.
У меня однажды был ASUS ROG, он глючил так, как не глючил ни один другой мой ноутбук. Не советую никому и никогда.
