Subject: DQ77KB 100% kworker or high pitch noise
Date: Fri, 16 Nov 2012 12:31:29 +0000	[thread overview]
Message-ID: <50A63221.4010806@gmail.com> (raw)

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
