Public bug reported: I'm running Lucid amd64 on the following hardware:
Manufacturer: TOSHIBA Product Name: Satellite T130D Version: PST3LC-001006 01:05.0 VGA compatible controller: ATI Technologies Inc RS780M/RS780MN [Radeon HD 3200 Graphics] Since linux-image 2.6.32-16.25 (I tried the kernel just before this one), when kernel initialize video drivers the display is somewhat corrupted. 1 pixel height ~ 100px width blue lines move around on the screen. It cover ~1% of the screen all the time. It do not appear if it's only in regular 80x24 console. If I prevent framebuffer to initialize, the symptoms appears when X start. I tried various mainline kernel with version taken here http://kernel.ubuntu.com/~kernel-ppa/mainline/ and thing is being fixed in kernel linux-image-2.6.34-020634rc1-generic. I diff'ed dmesg output between the latest working kernel compared to the broken one, here is what I see: > input: Video Bus as > /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:2c/LNXVIDEO:01/input/input5 < input: Video Bus as /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:2c/LNXVIDEO:01/input/input6 > platform radeon_cp.0: firmware: requesting radeon/R600_rlc.bin < EDAC MC: Ver: 2.1.0 Feb 20 2010 < EDAC amd64_edac: Ver: 3.2.0 Feb 20 2010 < EDAC amd64: This node reports that Memory ECC is currently disabled, set F3x44[22] (0000:00:18.3). < EDAC amd64: WARNING: ECC is disabled by BIOS.
