I can exactly confirm the same bug in my system. I have t2 disks sata, sda1 that is mount in my home dir and sdb1 that conteins the operating system. Some time during boot they get inverted (I imagine is a bios issue) and therefore initiramfs stops and drops me on a shell. Usually a reboot is enough to fix this problem
