--- Comment #11 from Dexuan Cui <decui@microsoft.com> ---
That first bad commit was reported by our test engineer. It turns out the
bisection in unreliable, but I do suspect something outside of the Hyper-V
drivers cause the panic, probably in the mlx driver, or the generic memory
management code.

@pete, thanks very much for your help! It turns out both 11.2 and the HEAD =
are
broken, but in my environment somehow I can't always reproduce it. I'll try=
 to
look into this next week.
