dmesg for offending commit
Dell U3011 monitor using DisplayPort connection to a Intel DQ67SW Motherboard
with an i7 2600 and Ubuntu 14.10, native resolution 2560x1600.
A DVI-D cable works, but DVI-D is limited to 1920x1200 on this cpu/chipset.
The bug flashes horizontal bars on screen every second or two while also making
some pop noise on DP audio.
I have bisected the offending commit
(24929352481f085c5f85d4d4cbc919ddf106d381). Kernel 3.19 throws a backtrace
which I could attach here if needed.
Sorry for my rusty english.</pre>
