We have the same camera on ThinkPad P16s Gen 4 AMD, I tried do suspend 5 times, I could not reproduce this issue, even I was waiting for more than 30 minutes.
BIOS: R2XET37W (1.17) EC: R2XHT30W Package: linux-image-6.14.0-1019-oem 6.14.0-1019.19 @pierre, It would be helpful if we could find a stable way to reproduce this issue. And this issue might be related to these factors. We need confirm if it's a driver issue or firmware issue. * USB Autosuspend Conflict: The Linux kernel tries to save power by putting USB devices to sleep. Sometimes, the camera's firmware doesn't wake up fast enough, causing the "Invalid Argument" error. Could you verify if the latest kernel could help this issue? sudo apt install linux-oem-24.04d Or the latest mainline kernel from https://kernel.ubuntu.com/mainline/v6.19-rc8/ * UVC Driver Timing: The uvcvideo driver might be attempting to talk to the camera before the USB bus is fully energized. Could the commands below let camera back? sudo modprobe -r uvcvideo sudo modprobe uvcvideo * Firmware State: The camera's internal controller might be stuck in a "low power" state. Could you help upgrade the firmware and try again? sudo fwupdmgr refresh sudo fwupdmgr update -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2139650 Title: Webcam disappears after long suspend [Lenovo T14 Gen6 AMD] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-oem-6.14/+bug/2139650/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
