Bug ID: 95328
Summary: System hangs for ~60 seconds on switching monitor
modes with amdgpu since Linux 4.5
Product: DRI
Version: XOrg git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel at lists.freedesktop.org
Reporter: guido-xorgbugs at unknownsite.de
Starting with Linux 4.5, the whole system will hang for about 60 seconds every
time the monitor configuration is changed. The system will be completely
unresponsive during this time, not even reacting to NumLock toggle on the
keyboard. The system stays responsive to pings from another machine, though,
and a music player app in the background keeps up it audio output.
This happens once during kernel bootup, once during the startup of the display
manager, once during startup of my desktop environment (which sets up a
multi-monitor configuration), every time my desktop environment enables or
disables screen blanking for inactivity and every time I make any changes to
the monitor configuration using xrandr or by connecting or disconnecting or
switching on or off any monitors on DisplayPort.
In dmesg, I get this output afterwards:

The system will continue after this point. The system clock has not lost any
time.
This is with CONFIG_DRM_AMD_POWERPLAY enabled. I haven't yet tested without
that setting.
