Hey!

I am unsure if I have the same bug. I am running a 3.16 with:

00:02.0 VGA compatible controller [0300]: Intel Corporation Xeon E3-1200 v3/4th
Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06)

When unplugging, I don't see anything in udev, but dmesg tells me:

Oct 20 21:11:31 eizo kernel: [  216.255211] [drm:intel_hpd_irq_handler] hotplug
event received, stat 0x00800000

Should I try to 3.17?
