Source: linux Version: 5.9.6-1 Severity: normal Deark Kernel Maintainers, Please enable CONFIG_SERIAL_8250_LPSS as a module or built-in driver in the kernel because without that the WD My Cloud PR4100 box runs the fan at full speed and this makes it practically unusable in small homes without manually compiling the module [1]. Cheers, Balint [1] https://community.wd.com/t/debian-linux-on-the-my-cloud-pr4100-pr2100/217141/11
