Re: drm-current-kmod-4.16.g20190424 hangs

Hi,

There’s not much of a clue in your boot message output.  I understand a recompile is necessary as the underlying linuxkpi data structure changed; likely breaking module interfaces.  This leaves me a bit concerned about mixing and matching versions of port and kernel.  If you are trying the latest binaries of both compiled with the same headers and seeing:

	device_attach: drmn0 attach returned 19

It’s that ENODEV where I would start.

If VT-d is off the recent changes to add bus_dma(9) to LinuxKPI should be essentially a no-op.  Actually ensuring that VT-d is disabled in your BIOS as it’s been repaired that the Intel GPU and DMAR are likely incompatible is probably the first thing to try.
