I was drawing svg in a text editor when, suddenly, Ubuntu 13.04 crashed on me displaying a few lines, similar to each other. Here are the two first :
[30714.772014] nouveau E[ 1265] failed to idle channel 0xcccc0000 [30714.772321] nouveau E[ PFIF0] CACHE_ERROR -- Ch 1/4 Mthd 0x012c Data 0x00000000
The next four were almost the same as the second one, with a few numbers changing. Could someone tell me why this happened and how to stop it from happening again?
