Hi, I found an NVMe stability issue on Orange Pi 4 Pro and a workaround that seems to fix it. Setup: Orange Pi 4 Pro 6 GB Armbian community 26.11.0-trunk.52 kernel 6.6.98-vendor-sun60iw2 Samsung MZVLW256HEHP 256 GB NVMe root filesystem on NVMe/ext4 Under heavier load, for example Docker builds/compilation, the NVMe sometimes disappears completely. Kernel messages: nvme nvme0: controller is down; will reset: CSTS=0xffffffff, PCI_STATUS=0xffff nvme nvme0: Disabling device after reset failure: -19 After that the root filesystem starts throwing I/O errors and even binaries from /usr/bin become unreadable. SMART looks normal and a direct sequential read test also passes. I added these kernel parameters: nvme_core.default_ps_max_latency_us=0 pcie_aspm=off pcie_port_pm=off Since then I have repeated the same Docker build and several whisper.cpp runs using all 8 CPU threads, and the issue has not come back so far. I also see this during boot: sunxi:pcie-6000000.pcie:[WARN]: Failed to get "power-gpios" PCIe still comes up normally as Gen3 x1 and the NVMe is detected. Looks like this may be related to PCIe/NVMe power management in the current vendor kernel or DT. Has anyone else seen this on Orange Pi 4 Pro / A733?
