Yuga - Sony Xperia Z¶
There exists basic mainline kernel support added by Sony. This possibly could become a reference device.

Kernel & Hardware¶
Mainline (v4.15-rc9 as of writing)¶
The kernel will start and there is already UART and USB debugging implemented for this device. There also has been worked on riva, which is used for connectivity like WiFi, Bluetooth and FM, but there is no documentation of what really works.
LineageOS kernel (v3.4.113)¶
This is just the original Sony kernel with some security fixes, updates and back ports. Unfortunately the LTS has ended, so 3.4.113 is the last version.
You can always get into fastboot by holding the power button and the volume up button until the device vibrates three times, then only press the volume up button and you’ll get into fastboot. If you use a LineageOS/CyanogenMod boot image you can also press volume up or down, when the LED turns pink on startup.
I always had to flash TWRP to the boot partition to get into the recovery again. Currently I don’t know if there is any way to get into the recovery in a simpler way.
There’s no strange behaviour, except the way to get into fastboot or recovery.
