6.6.74 is broken too. (That's the revision that the ARM tests want).
So it broke somewhere between .56 and .74 which narrows the bisect a little.

In Gitlab, both AMD and Intel are failing in roughly the same way.
Something else goes wrong in QEMU even with my patch for the hypercall,
and Linux eventually crashes. Lots of unhandled memory read/write in
0x1bfffe000 - 0x1bfffeff8, which is marked unusable for dom0. I trimmed
lots of the consecutive "unhandled memory" from the attached log
(313KB->22KB)
