Hi,
we currently have a temporary solution:
Please comment out the following line in Linux_for_Tegra/source/public/kernel/kernel-4.9/kernel/printk/printk.c
error = syslog_print_all(buf, len, clear);
it’s line 1492 on my side, and inside function do_syslog(), make sure to allocate it correctly if the line number is different. After the change, follow the developer guide to apply rt patches and build the kernel.

The device should boot up correctly without hanging up, and display should also be working. But note that there are still two limitations (hence temporary):
- Use either headless mode or a 1080P monitor, as there’s still some compatibility issues with 4K monitors. Not sure if 2K works, you may try it yourself.
- Do not change resolution when connected to a real monitor, the Ubuntu Settings APP will crash when you tryto access the display section.
