| Summary | AMD Xorg start failes with non-4K page sizes |
| Product | DRI |
| Version | unspecified |
| Hardware | PowerPC |
| OS | All |

Have two nearly-identical boxes, both running Debian testing with a 4.16
kernel, only major difference is one is configured with a 4k page size, one
with Debian's default 64K page size (on PPC64LE). This results in a corrupted
output when running X (with a non-corrupt mouse overlayed on top) and the
following WARN in dmesg:
