That includes booting via USB media. This is not limited to FreeBSD: Linux and Windows 11 too, for example. No OS is known to operate without such problems. QUOTE of https://github.com/worproject/rpi5-uefi?tab=3Dreadme-ov-file : In ACPI mode ACPI support is currently under development and limited to a few devices = that have existing driver bindings. Warning USB is unreliable and may cause data corruption on all supported OSes. = We're currently investigating this issue, see: #3. END QUOTE #3 is: https://github.com/worproject/rpi5-uefi/issues/3 EDK2's USB I/O for its own purposes uses polling and seems to work okay. =3D=3D=3D Mark Millard marklmi at yahoo.com
