The rest of this dump can provide useful information.

Also what was logged in dmesg? It will have the reason why the kernel
hated this submit.

Also... what hardware do you have (lspci -nn -d 10de: output would be
great)? libdrm version? mesa version?

How big is your texture? How much VRAM do you have?
