I am not sure what we break here if we drop the irq-off. It waits to sync
with the interrupt and expects no interruption after that. What about if
we skip this mmio_flip thing entirely? Either via modprobe or kernel
commandline
i915.use_mmio_flip=-1
should do the trick. Either way
/sys/module/i915/parameters/use_mmio_flip
should be -1. Could you please try and test?
