Subject: [Bug 103913] DRM/Radeon driver not resilient to poor monitor connections
Date: Sun, 26 Nov 2017 11:15:42 +0000 [thread overview]
Message-ID: <bug-103913-502@http.bugs.freedesktop.org/> (raw)

Bug ID: 103913
Summary: DRM/Radeon driver not resilient to poor monitor
connections
Product: DRI
Version: XOrg git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
Assignee: dri-devel@lists.freedesktop.org
Reporter: roger@beardandsandals.co.uk
Disconnecting and reconnecting HDMI/DVI connectors, or a loose connection, can
cause the driver to stall in a loop with the following messages being logged
approximately every 500ms in syslog.
Nov 25 16:13:30 dragon kernel: [363196.855813] radeon 0000:02:00.0: ring 0
stalled for more than 1710608msec
Nov 25 16:13:30 dragon kernel: [363196.855818] radeon 0000:02:00.0: GPU lockup
(current fence id 0x0000000000284cb5 last fence id 0x0000000000284cb6 on ring
0)
This causes the screen to blank. A reboot is required to clear this.
It would seem more sensible to reset the driver if it has been locked on the
same fence for a long time.
