Ever since we swapped fi-ctg-l9400 for another one
(https://bugs.freedesktop.org/show_bug.cgi?id=101089), we started randomly
hitting an assert when running igt at gem_mmap_gtt@basic-small-bo-tiledx:

file gem_mmap_gtt.c:518:

PAGE_SIZE) == 0
Subtest basic-small-bo-tiledX failed.

So far, it has happened 4 out of the 5 runs of the new machine.
