>Description:
When booting NetBSD 9.0_BETA on the Olimex Teres laptop ( https://www.olimex.com/Products/DIY-Laptop/ https://github.com/olimex/diy-laptop https://github.com/OLIMEX/DIY-LAPTOP/raw/rel3/HARDWARE/A64-TERES/TERES-PCB1-A64-MAIN/Rev.C/TERES_PCB1-A64-MAIN_Rev.C.pdf ) The builtin display will show u-boot output, followed by the NetBSD/evbarm EFI Boot prompt. All further output is only sent along the serial line and not on the display (dmesg, login prompt, etc).

Here is the dmesg output:
