Hi, I have a laptop ASUS ROG Strix G15 Advantage Edition G513QY-HQ007. But it is impossible to use without AC power because the system losts nvme when I disconnect the power adapter. Messages from kernel log when it happens: nvme nvme0: controller is down; will reset: CSTS=0xffffffff, PCI_STATUS=0x10 nvme nvme0: Does your device have a faulty power saving mode enabled? nvme nvme0: Try "nvme_core.default_ps_max_latency_us=0 pcie_aspm=off" and report a bug I tried to use recommended parameters (nvme_core.default_ps_max_latency_us=0 and pcie_aspm=off) to resolve this issue, but without successed. In the linux-nvme mail list the last advice was to try the "pci=nocrs" parameter. But with this parameter the amdgpu driver refuses to work and makes the system unbootable. I can solve the problem with the booting system by blacklisting the driver but it is not a good solution, because I don't wanna lose the GPU. Why amdgpu not work with "pci=nocrs" ? And is it possible to solve this incompatibility? It is very important because when I boot the system without amdgpu driver with "pci=nocrs" nvme is not losts when I disconnect the power adapter. So "pci=nocrs" really helps. Below that I see in kernel log when adds "pci=nocrs" parameter: amdgpu 0000:03:00.0: amdgpu: Fetched VBIOS from ATRM amdgpu: ATOM BIOS: SWBRT77321.001 [drm] VCN(0) decode is enabled in VM mode [drm] VCN(0) encode is enabled in VM mode [drm] JPEG decode is enabled in VM mode Console: switching to colour dummy device 80x25 amdgpu 0000:03:00.0: amdgpu: Trusted Memory Zone (TMZ) feature disabled as experimental (default) [drm] GPU posting now...
