Hi,
I've been finding that kmemleak reports that i915 is leaking gem
buffers (although it takes about 20 minutes before the supposed leaks
occur). The leaks normally occur in batches of 13 and seem to require
chrome to be running looking at a page like google.com while a
gnome-terminal is also present. It is important that the screensaver is
postponed using something like
watch "xdg-screensaver reset" .
A batch of the leaks are below:
