Sure.
Since I could not revert arjans patches without conflicts, I started
checking out older versions. My first try was
e427fe042cf90c0652eed9a85e57a8fd8af89890 (without PIO, with async patched)
was successful. The problem went away. So it was triggered by the 32bit PIO patch.
Do you still need a test result without the async patches?
