When booting with the newest kernel from the amd-staging-4.7 branch from https://cgit.freedesktop.org/~agd5f/linux/, all connected monitors will go blank and stay blank indefinitely. The power indicator on the monitors will start to blink as if there was no signal. This is with commit 680da8633ae17cdea8fddd1ede87253325c8ca25. With an older commit, d330e1e9c232895dbd0c183a647d41d54ecc0884, this branch still works. DAL is enabled in the config in both cases. The graphics card is a Sapphire Nitro Radeon R9 380X. There are three monitors connected in total, one to the DVI-I port, one to the DVI-D port and one to the DisplayPort. I am using this particular branch as a workaround for the bug described in https://bugs.freedesktop.org/show_bug.cgi?id=91202
