Can you please boot with drm.debug=0xe added to your kernel cmdline, reproduce the issue and then attach the complete dmesg? You might need to increase the log buffer size with log_buf_len=4M or so. We have a bunch of changes queued up for 3.17 in the panel power sequencing which might affect your machine. Please also test the latest drm-intel-nightly git branch from http://cgit.freedesktop.org/drm-intel Thanks, Daniel > > > Sincerely, > > Adam Skillen > > > > > Hardware: > Dell System XPS L502X/0NJT03,
