Thanks for the tip! I'll give that a try.
Unfortunately, it turns out that rootwait/delay doesn't help. The problem occurs even
earlier: U-Boot cannot find any bootable devices. Therefore, I need to add a delay in
U-Boot.
But it is not a big deal - I very rarely power-cycle my Wandboard. It is on a UPS, and
runs 24/7. It is only power-cycled if I have to replace hardware.
