I got some oob help as well and am in the process of debugging some of the hardware support. In case anyone else is interested, the kernel (both 7.5-stable and -current) hangs during boot at ohci; disabling that allows boot and install to proceed. I'm seeing unexpectedly poor performance with dwqe, and neither of the rge interfaces seems able to acquire a dhcp lease. I also am seeing unexpectedly low performance compared with an rpi4 in the LibreSSL speed test; AES, SHA1, and SHA2 are only ~clock-speed faster, and not Using ARMv8 ISA faster. Thanks again for the reply. s.
