First time since years I switched the dusty Rock64 on :-) yes, you=E2=80=99re right, still not fixed : dmesg: .. clknode_link_recalc: Attempt to use unresolved linked clock: hdmi_phy Cannot get frequency for clk: hdmi_phy, error: 9 =E2=80=A6 So you can file a bug report to: https://bugs.freebsd.org = <https://bugs.freebsd.org/>; You can attach dmesg there (or what I would prefer: send dmesg to = https://dmesgd.nycbug.org<https://dmesgd.nycbug.org/>) I guess you don`t want to port any linux drivers at first attempt :-) = but instead fix the issue=20 to get the framebuffer driver working( with it`s restrictions e.g. no = 4K) Regards K. > Am 20.09.2024 um 19:22 schrieb Christoph Pfaller = <pfaller@protonmail.com>: >=20 > Hello! >=20 > I recently switched to FreeBSD on my Rock64 due to appearing kernel = panics when running the board with Linux.
