Hi Bryce,

For any bugs showing mysterious Intel-graphics crashes with libdrm 2.4.17,
please encourage the bug reporters to re-try with libdrm 2.4.18 (just
released today). It includes the commit below.

I'll mark this as NEEDINFO for now. Please update the bug (and clear
NEEDINFO) after adding results of testing with libdrm 2.4.18.

-Carl

    intel: Handle resetting of input params after EINTR during SET_TILING
    
    The SET_TILING is pernicious in that it overwrites the input arguments
    following an error in order to report the current tiling state of the
    buffer. This caught us by surprise as we then fed those arguments back
    into to the ioctl unmodified following an EINTR and so the kernel then
    reported success for the no-op. We interpreted this success as meaning
    that the tiling on the buffer had changed so updated our state and
    started using the buffer incorrectly in the new tiled/untiled manner.
    This lead to all sorts of random corruption and GPU hangs, even though
    the batch buffers would look sane (when the GPU had not wandered off
    into forbidden territory).

Hi Carl,

2.4.18 seems to have fixed this problem. Thanks!
