Weird coincidence, that is a bug that's been in the tree for months
but was only reported to me earlier this week. Try reverting
commit a82fd5a4ec24d923ff1e -- that should fix it.
https://lore.kernel.org/qemu-devel/CAFEAcA_i8x00hD-4XX18ySLNbCB6ds1-DSazVb4yDnF8skjd9A@mail.gmail.com/
has the explanation.
