On Fedora 25 with a 4.8.0-0.rc6 kernel (with the EDID detect patch for RPi3) we're setting the following crash with a low quality monitor on a Raspberry Pi 2 (not tested on the RPi3).

The monitor is: Haier 22 inch, hl22kn1 http://www.bradstv.com/en/catalog/product/50116-Haier-HL22KN1

EDID data: EDID (in hex): 00ffffffffffff002245010001010101 0a100103807341960acf74a3574cb023 09484c2fce0031404540614001010101 01010101010164190040410026301888 360000d052000018000000fd0038551f 3c08000a202020202020000000fc0048 414945522054560a20202020000000fc 000a20202020202020202020202001b6 020317f1448405030223090707830100 0065030c001000011d007251d01e206e 285500c48e2100001e011d8018711c16 20582c2500c48e2100009e8c0ad08a20 e02d10103e9600c48e210000188c0ad0 8a20e02d10103e9600138e2100001800 00000000000000000000000000000000 000000000000000000000000000000ba

https://lists.freedesktop.org/archives/dri-devel/2016-September/119658.html should do it hopefully.

Fix is merged to airlied's -next.

For reference I pulled this into Fedora already and it'll be in the 4.8.1 kernel. When the person with the monitor is back from PTO I'll get it confirmed as fixed.
