Description: After upgrade to version 3.15.1-1 I get a "[drm:cpt_serr_int_handler] *ERROR* PCH transcoder A FIFO underrun" on every boot. It seems that only Intel-Ivy-Bridge-boards are affected. Version 3.14.6-1 has not this issue.


Additional info: After each reboot KDE reports that an audio equipment such as "HDA Intel PCH (ALC892 Analog)" or "HDA Intel PCH, ALC892 Analog (2.1 surround output, front and subwoofer speakers)" is missing, even if the devices are present and working.


Steps to reproduce: Update to kernel version 3.15.1-1
