I have a NVMe SSD connected via PCI-E adapter; when I try to install OS on it - everything seems to work fine, but my PC doesn't go to hibernate mode. It just gets stuck with display off and power LEDs on forever.
Any ideas?
A kind of semi-solution I've found so far... the hibernation problem doesn't happen when I install the PCIe adapter with SSD in a PCIe slot 3. It works at half max speed in this case, though.
