Presuming it is bug 73351, it should be fixed by

    sna: Nullify pixmap->devPrivate.ptr after promoting CPU bo to GPU

    When we convert a CPU bo into a GPU bo, we need to remove any dangling
    shadow pointers we use for devPrivate.ptr. Whilst the bo remains alive
    these are incoherent, but if we ever replace the GPU bo (for example to
    change tiling for DRI2) then the dangling pointer becomes invalid and
    will explode on next use.

The concern is that you have a different stacktrace which may indicate another
issue. In any case the extra assertions added for #73351 should also help here.

Please try testing with xf86-video-intel.git and see if that resolves the issue
or gives us more debug information.
