I have 2 laptops with identical cases if not identical internals. One is my everyday -current/amd64 laptop. I have been trying to netboot the other one which keeps failing to load the kernel over nfs, at the stage where the twiddle is still printing the first number. (I think there are normally 3.)
pxeboot_bin and the kernels are all a few day old -current/amd64. I tried GENERIC, GENERIC with DEBUG (no extra printing), a compressed GENERIC, and the kernel from the working laptop. Repeating the netboot, the load would always stop at the same place for that kernel. (Different places for different kernels, so not "network transferred given number of bytes".) Compressed and corresponding uncompressed kernels stop at the same place. I also tried a GENERIC/i386 kernel (in case of "can't cope with instruction XXX"), and the same happened. On a whim, I tried FreeBSD-11.0-CURRENT-amd64-20150716-r285616-bootonly.iso.xz which successfully netbooted. Any suggestions on what might be going on? Cheers, Patrick
