dmesg log
==System Environment==
--------------------------
HDMI monitor: ASUS VS239HR
BIOS: V59
Regression: No. This issue happens with V49 BIOS.
Non-working platforms: BSW
==kernel==
--------------------------
-testing: drm-intel-testing-2015-04-23 (fails)
==Bug detailed description==
-----------------------------
After system boots, dmesg shows floods of hotplug events:
[ 2.430657] [drm:intel_hpd_irq_handler] hotplug event received, stat
0x00000040, dig 0x00000000
[ 2.431178] [drm:intel_hpd_irq_handler] hotplug event received, stat
0x00000040, dig 0x00000000
[ 2.431718] [drm:intel_hpd_irq_handler] hotplug event received, stat
0x00000040, dig 0x00000000
......
I first saw this issue since the BIOS upgraded to V49, not sure it's a BIOS
issue or kernel issue. Submit this issue for reference.
==Reproduce steps==
----------------------------
1. boot BSW
2. dmesg |grep hotplug
[ 2.430657] [drm:intel_hpd_irq_handler] hotplug event received, stat
0x00000040, dig 0x00000000
