Hi Andreas,

The following is the result of the test so far. I would continue to
see what happened there.

1. Boot on openSUSE-Tumbleweed-RISC-V-JeOS-hifiveunleashed.riscv64.raw.xz
w/ plugging ethernet cable
  - It seems that I encountered a different situation with you, my
system hung up and I didn't see the boot message you mentioned yet.

2. Boot on kernel image which built by opensuse defconfig with
changing CONFIG_MACB to y instead of m
 - Although I got some problem for mounting the root filesystem on
this image now, but I didn't hang up at the message you mentioned, I
could go through after macb driver initialization

3. I check the patch set of supporting fu740, it shouldn't impact
fu540, I'm going to dump and comparing the prci content and give more
testing.
