Previously I had the affected tests disabled and never tracked down the problem.
Since the problem is now spreading to additional tests, I finally tracked it down,
that is all.

I run all tests during boot, not from the command line. I also use the -bios
command but don't recall any issues with the console. I specify the
console on the qemu command line; depending on the qemu machine it is either
ttyS0 or ttyAMA0. The init script then finds and selects the active console.

I can't really see what that command is actually doing ;-).

I'll just keep the affected tests disabled on arm64 for the time being.
