Bug ID: 98997
Summary: Invalid ioctl during Xorg startup
Product: xorg
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau
Assignee: nouveau at lists.freedesktop.org
Reporter: reptm at mail.com
QA Contact: xorg-team at lists.x.org
OS: Ubuntu 16.10
Kernel: 4.8.0-28-generic
xorg-server: 1.18.4
cpu: Intel(R) Core(TM) i7-3720QM CPU @ 2.60GHz
After connecting UDL device and restarting Xorg, Xorg tries to send invalid
ioctl to that device.
Looks like Xorg enumerates existing drm devices and performs driver's
platformprobe function on them regardless of their type.
