Doc Type: Bug Fix
Doc Text:
Some BIOS firmware versions could leave the "Frame Start Delay" bits of the PIPECONF register in test mode on selected Intel chipsets. Consequently, video output on certain Lenovo laptop series, such as T41x or T42x, became corrupted (for example, the screen appeared to be split and shifted to the right) after upgrading VBIOS from version 2130 to 2132. This update corrects the problem by resetting the "Frame Start Delay" bits for the normal operation use in the DRM driver. Video output of the previously affected Lenovo models is now correct.

Comment 5 Dave Airlie 2012-11-14 16:40:02 EST
are these patches marked for stable upstream?

if not, can this happen prior to us including them, so we know they get more broad testing?
