Priority: medium Bug ID: 71796 Assignee: dri-devel@lists.freedesktop.org Summary: Hardware assisted (VDPAU) decoding of MPEG-2 causes GPU lockup - Radeon HD6950 Severity: normal Classification: Unclassified OS: Linux (All) Reporter: libgradev@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/DRI/R600 Product: Mesa
Created attachment 89477 --> https://bugs.freedesktop.org/attachment.cgi?id=89477&action=edit DMESG output showing hardware info and lockup.
Playing back MPEG-2 compressed video causes a GPU lockup and reset. This happens about 9 times out of 10 upon start of playback - the other time playback starts fine.
About 4 out of 5 times the reset is successful and playback begins a catchup phase before continuing normally - otherwise it results in a complete system freeze.
If playback actually starts it continues fine.
Using VDPAU assisted playback via XBMC. Using software only playback works fine every time. h264 playback seems unaffected.
