While writing = 1 to it seems fine. There's also an issue of system crash and reboot after echo = 1 | tee ../pci/rescan.=20 Steps to Reproduce: echo 1 | tee ../remove(dgpu path) echo 1 | tee /sys/devices/platform/asus-nb-wmi/dgpu_disable echo 0 | tee /sys/devices/platform/asus-nb-wmi/dgpu_disable echo 1 | tee /sys/bus/pci/rescan Observations: Did the above steps 10 times, everytime it produced an Input/Output error a= nd everytime system crashed and rebooted, during pci rescan. journalctl -p 3 showed an ACPI error after writing 0 to dgpu_disable. journalctl -p 3, lspci are attached. --=20 You may reply to this email to add a comment.
