| 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.
