The workaround didn't work for me. My HDMI audio interfaces still weren't found by the kernel.
While if eliminates the kernel message about duplicate symbols, the kernel now can't find the routines needed for the power_well stuff because It thinks those are in the bdw driver and so it doesn't initialize the HDMI audio devices. The issue seems to be that with two drivers with the same symbols (i915 and i915_bdw) , moddep creates symbols files with some aliases pointing to i915_bdw and some pointing to i915. I had to rename i915_bwd_ko file to i915_bwd_konomore and then run depmod -a to get a reasonable symbols file that only has aliases to load i915.ko. After that, my HDMI audio interfaces were working again. It there a way to tell depmod to ignore certain kernel modules? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1317865 Title: 8086:0412 [Gigabyte Z87X-UD3H] bug in the Ubuntu backport of BDW stuff for 14.04, where it tries to treat your hardware as Broadwell, and gets confused when your hardware behaves like Haswell.
