Priority: medium Bug ID: 60254 Assignee: dri-devel@lists.freedesktop.org Summary: agd5f wip kernel Oops when provoking GPU lock. Severity: normal Classification: Unclassified OS: All Reporter: lists@andyfurniss.entadsl.com Hardware: Other Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI
The GPU lock with Rv670 and openarena is nothing new - it seems to have been a feature for almost a year (I haven't used rv670 for most of that time).
On noticing the new gpu reset code in drm-next-3.9-wip I decided to provoke it on my AGP box and got -
