Hello, This is my first time reporting an issue in the kernel. *Device Details*: * Asus Zephyrus G14 (||||||*GA402RJ*) * Latest BIOS * Arch_x86_64 * Kernel: 6.6.9 * Minimal install using archinstall *ISSUE*: Using /dgpu_disable /provided by _asus-nb-wmi _to disable and enable dedicated gpu, causes system crash and reboots, randomly. 9/10 times writing 0 to dgpu_disable will produce an Input/Output error, but the value will be changed to 0, half the time system will crash and reboot. While writing 1 to it doesn't produce an error, I have observed system crash twice just after that. *Steps to Reproduce:* * Remove dpgu: echo 1 | sudo tee ../remove (dgpu path) * echo 1 | sudo tee /sys/devices/platform/asus-nb-wmi/dgpu_disable * echo 0 | sudo tee /sys/devices/platform/asus-nb-wmi/dgpu_disable * echo 1 | sudo tee /sys/bus/pci/rescan After writing 0 to dgpu_disable, there's an entry in journal about an ACPI bug. Output of 'journalctl -p 3' and lspci is attached.
Hi, Can you share the output of "acpidump" and the content of "/sys/bus/wmi/devices/05901221-D566-11D1-B2F0-00A0C9062910[-X]/bmof"? The bmof files contain a description of the WMI interfaces of your machine, which might be important for diagnosing the error. Thanks, Armin Wolf
