SATA hotplug issue
by afronteau from LinuxQuestions.org on (#5K2D3)
Hi, I've build a kernel 4.19 with buildroot. When I start the NUC with a SATA disk (AHCI) plugged, I can unplugged it and plugged it can successfully and it is always recognized by udev rules that mount/unmount it. My problem occurs when I start the NUC without the SATA disk, then when I plugged it hoping that it triggers the udev rules, it does not happen doing nothing (the disk consumes power energy). Do I misunderstand something about SATA hotplug ?
