Hello, I reported this bug also against drm-intel [1] and it has been fixed by a patch found in comment 51 of that bug [2]. Now, the patch has also entered kernel 4.4-rc4
I recompiled the module manually with the patch above on linux-4.2 from stable-bpo and it fixes the issue. Do you think this could be backported to the kernel version present in jessie (3.16) ? The patch cannot be applied directly to that version. Kind regards [1] https://bugs.freedesktop.org/show_bug.cgi?id=90725 [2] http://cgit.freedesktop.org/drm-intel/commit/?id=a53f2afb7e3dfc2c7acbb0c015b44783d99d8119
