DQ77KB 100% kworker or high pitch noise
Hi,
I have an Intel motherboard DQ77KB which has a 2-pin header which says panel_off and a fresh Ubuntu 12.10 (3.5.0-18-generic
) install and a display connected via Displayport (DP1, not eDP1). If I connect the header in the running system a kworker process pops up with 100% cpu usage. If I leave the header unconnected no kworker process runs, which is good, but a pitch noise comes from the motherboard, probably from some voltage regulators.
I am no programmer, and I don't understand much about the kernel. But I would like to get the problem solved. If I can be any help, please let me know.
Kind regards
Timo

Given that you are running the Ubuntu disto, I suggest you file a bug in their bug tracking system, as they are the best ones that can help track down this issue for you.
Best of luck,
