Package: linux Version: 4.19.0-4 + Severity: grave A regression was introduced in 4.13-rc1(Mainline) and newer kernels. This regression caused battery drain during system suspend, hibernation or shutdown for some PCI devices that are not allowed by user space to wake up the system from sleep (or power off).
It has been fixed in the upstream kernel, but still present in buster and bullseye. Kindly patch the debian kernel. https://patchwork.kernel.org/patch/10387667/ Thanks, Gopal.
