Is anyone else failing to boot Ubuntu?
Trying with two different brand SD cards, two different power sources, and monitoring its boot sequence with a serial interface, if the machine doesn't repeatedly reboot then it will hang with gibberish as its last gasp:
[ 1.802210] usb usb2: New USB device found, idVendor=1d6b, idProduct=0003
[ 1.802822] usb usb2: New USB device strings: Mfr=3, Product=2, SerialNumber=1
[ 1.803463] usb usb2: Product: xHCI Host Controller
[ 1.803892] usB???????f?f
Fails both with the most recently released 16.04 and 18.04 images. Perhaps of interest: the point in the boot sequence at which it hangs/reboots changes, not consistently though, if I connect a display or ethernet.
It does boot the Android 8.1 image, but the system is as good as a paperweight to me running that OS, so getting proper Linux working is essential. If it helps, here's captured example output using the ROC-RK3399-PC-UBUNTU18.04-GPT-SDBOOT-20190304-1136 image.
Any thoughts? Thanks in advance.

I had problems booting Ubuntu at first, but Android would boot just fine. Turns out that the power supply was the issue. There are a few postings in this forum about the power supply. I think I might have tried a 30w supply, but needed a 45w supply for Ubuntu.
