--0000000000008f61da0622953e90 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hello to everyone. Recently I've bought the RockPro64 with the RockChip RK3399,this one : https://pine64.org/devices/rockpro64/ I would like to know if FreeBSD is affected by the same bug,please. I can't use it if the HDMI doesn't work.
