https://bugzilla.kernel.org/show_bug.cgi?id=60791 Bug ID: 60791 Summary: Display corruption with Radeon driver during boot and on desktop Product: Drivers Version: 2.5 Kernel Version: 3.10.5 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: hallbw@xxxxxxxxx Regression: No Created attachment 107302 --> https://bugzilla.kernel.org/attachment.cgi?id=107302&action=edit showing the problem during boot As of vanilla kernel 3.10.5, I am seeing green speckled display artifacts during boot, and on my desktop. During boot and on solid backgrounds they take the form of green arcs in multiple places; other times they take the form of hashed green lines in small areas of the display (such as on the Phoronix website rendered in Chromium). This corruption does NOT occur on kernels 3.10.4 and below, nor on 3.9 kernels (tested up to 3.9.11 vanilla). I think the corruption is somehow happening AFTER the display buffer, because when I take a screenshot, the green speckling is only visible when booted to a problematic kernel- if I reboot into a kernel with the issue, when I display the screenshot I previously took the corruption is not visible. I have tried using "radeon.audio=0" on the kernel command line, but that had no effect. I am not using HDMI video or audio, only DVI. Since I couldn't take a screenshot, I took some pictures with a camera. Hard to see due to focus and because the short green horizontal lines of the corruption flicker madly. System details: x86_64 Solydx 2013.08.06 (Debian jessie/sid rolling base) BIOSTAR A785GE with onboard Radeon HD4200 video AMD Phenom II X4 940 CPU 4GB DDR2 memory More details attached. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
