Hi Rodrigo,
I verified your branch kernel: 
http://cgit.freedesktop.org/~vivijim/drm-intel/log/?h=psr-baytrail, on my
broken BDW SUT, cannot produce this issue, thanks.

Used kernel detail info: 
[root at x-bdw04 ~]# cat /proc/cmdline
BOOT_IMAGE=kernels//prts/d85f8b99bf0e8d218260e86de31b6b022acd4f18/bzImage_x86_64_debug
root=/dev/sda4 drm.debug=0xe i915.enable_psr=1
modules_path=kernels//prts/d85f8b99bf0e8d218260e86de31b6b022acd4f18/modules_x86_64_debug/lib/modules/3.14.0-rc7_prts_d85f8b_20140326_debug
