Please do not put unrelated bugs here. Leave this for incoherency on hsw. Track the aliasing-ppgtt eviction failure elsewhere.

Just the normal stab in the dark,

    drm/i915/gt: Try an extra flush on the Haswell blitter
    
    On gen7, including Haswell, the MI_FLUSH_DW command is not synchronous
    with the command streamer nor is there an option to make it so. To hide
    this we add a large delay on the CS so that the breadcrumb should always
    be visible before the interrupt. However, that does not seem to be
    enough to ensure the memory is actually coherent with the read of the
    breadcrumb. The breadcrumb update is a post-sync op... Throw in a
    preliminary MI_FLUSH_DW before the breadcrumb update in the hope that
    helps.
