<pre>You can try something like:
echo 15 > /sys/kernel/debug/dri/0/i915_hpd_storm_ctl
which should at least turn off the hpd irq for a few seconds after it's
detected 15 spurious hotplug interrupts within one second. Obviously since the
machine is generating these things constantly it'll ping-pong between the two
states, but should at least let it sleep for a few seconds every now and then.</pre>
