Kernel with DEBUG option drm.debug=14
Yes, I'm able to reproduce the bug every time I log in. I use use the command $dmesg |grep drm $ so i did the mistake. I fully repost the syslog file names kern.log.

Created attachment 164481 [details] This is the kern.log backtrace I configure and compile many time the Linux vanilla kernel. synce the first time i recompile the kernel I get the display go off and soon go on after logging in my debian. Now, after 3.18 kernel version, i note that syslog put this error: [drm:i9xx_check_fifo_underruns] *ERROR* pipe A underrun I put the backtrace. My CPU is an Intel U4100 an dual core Cantiga i think. My graphic card is clearly an Intel Integrated If I dmesg |grep vga : [ 0.197091] vgaarb: setting as boot device: PCI:0000:00:02.0 [ 0.197091] vgaarb: device added: PCI:0000:00:02.0,decodes=io+mem,owns=io+mem,locks=none [ 0.197091] vgaarb: loaded [ 0.197091] vgaarb: bridge control possible 0000:00:02.0 [ 0.344654] vgaarb: device changed decodes: PCI:0000:00:02.0,olddecodes=io+mem,decodes=io+mem:owns=io+mem .
