--- Comment #15 from Damien Lespiau <damien.lespiau at gmail.com> ---
Could you post your patch to the intel-gfx mailing list for review?

One thing that is important to check as well is if we correctly re-initialize
the DDI PHY registers, could you check the value of register 0x64E00?

$ sudo ./tools/intel_reg read 0x64E00

Making sure that's not set to the reset value will avoid hard-to-debug bugs
down the line.
