dmesg with drm.debug=0xe in kernel command line

I have a DELL XPS13 laptop and an external monitor. They used to work well on
linux kernel 3.8. Recently, I upgraded to kernel 3.9 and found the resolution
of the external monitor could not be configured correctly. I checked kern.log
file and found a lot of error messages look this:

Jul  2 15:27:40 debian kernel: [   39.181113] [drm:intel_dp_i2c_aux_ch] *ERROR*
too many retries, giving up

I downloaded the latest kernel from drm-intel-nightly
(drm-intel-a59485486882b9867bdcb1fe41cfdcba291c6585,July2nd,2013). However, the
issue is still there. The dmesg information with drm.debug=0xe is attached. 

Since this issue was also reported by others and it was there for more than
three months, hope it can be set as a high priority investigation from the
development team.

Please let me know if you want me to try more patches.

Thanks,
Wei</pre>
