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:
(gem_mmap_gtt:3095) CRITICAL: Test assertion failure function test_huge_bo,
file gem_mmap_gtt.c:518:
(gem_mmap_gtt:3095) CRITICAL: Failed assertion: memcmp(ptr , linear_pattern,
PAGE_SIZE) == 0
Subtest basic-small-bo-tiledX failed.
