Hi All, With Linux v3.14-12042-g69cd9eba3886 I get an oops from the bcma module on the MacBookPro 10,2 I have here. This works fine with Linux v3.14-7333-g59ecc26004e7. There have been no changes between those two versions to bcma itself, but the GPIO merge did go in that window. I can attempt to do a bisect tomorrow, but looking over some of the GPIO commits it seems pretty relevant to the ACPI GPIO changes. I'm hoping someone here has an idea on what the issue might be and has some possible things for me to test for fixes. I've transcribed the oops below by hand from a pic I took of the oops because it doesn't wind up in the logs.
