Please find the trace and the kernel CL below.
Note, the domU get stuck into a bootloop with this assertion as the
situation will come back after domU restart and only dom0 reboot can
get the situation back to normal.
The trace I captured below is within the boot loop. I suspect the
initial trigger may look different. Will give it another try soon.
