Public bug reported:
Binary package hint: xserver-xorg-video-intel
This on happens on my intel g45 machine (not on my 965 laptop which also
uses the intel driver).
Basically /bin/dd, /sbin/klogd, /sbin/syslogd constantly take up 30-100%
of a single core on my machine. This happens because some strange error
is being fired constatly from the intel xorg driver. My dmesg has an
endless flood of errors like this:
