| I am not sure what we break here if we drop the irq-off. It waits to sync

| 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?
I will need to test that during the weekend, but I can surely test.
Luis
