It seems to be a bit of a random problem. It does not occur every time, = but when it does, it is "caused" by normal usage, e.g. working with a = document in LibreOffice and browsing the web. As a side note, I have been testing i915 for a few months now, and it's = only after the merge to HEAD that this problem has occurred to me. I = decided to switch back to HEAD once the new i915 driver was committed.=20 Whole contents of core.txt.9 is available from here: = https://www.dropbox.com/s/zbkwlqvp4hi3ukc/core.txt.9?dl=3D0 (I tried to = include it as an attachment, but I got a message from the owner of the = mailing list that said the message was too big, so I shared the file on = Dropbox instead). Like I said, it may or may not be the same problem as the one Frederic = Chardon has, but if it is, I hope this will help identifying and/or = solving the problem. Anders
