Date: Sun, 01 Mar 2015 19:02:03 +0000 [thread overview]
Message-ID: <bug-94081-2300@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=94081
Bug ID: 94081
Summary: [radeon 3.18 regression] GPU reset recovery fails
Product: Drivers
Version: 2.5
Kernel Version: 3.18.x
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: jan.vesely@rutgers.edu
Regression: No
starting with kernel-3.18 (fedora version) fails to recover from OpenCL induced
GPU loockup.
reproducer:
Run noise-hurl.xml OpenCL test in gegl library:
[354672.707822] radeon 0000:01:00.0: ring 0 stalled for more than 10020msec
on 3.17 (fedora again) I observe one or two display flashes, and full recovery.
starting with 3.18 I see the flash, and the dispaly stays frozen. the task
itself(gegl) stays in uninteruptible state
Here are the relevant lines from dmesg on 3.18:
