<pre>On a MacBookAir with GeForce 9400M (C79) when X starts after booting (using
Enlightenment with compositing) a horizontal bar in the middle of cursor (about
1/3 of cursor height) is transparent instead of showing cursor.
At the same time, kernel log is being filled with following error:
nouveau E[ PFB][0000:02:00.0] trapped read at $addr on channel $fixed_addr
BAR/PFIFO_READ/FB reason: PAGE_NOT_PRESENT
$fixed_addr is always the same (0x0000fee0) and $addr changes each time (e.g.
0x000040fe00 then 0x000040fe0c then 0x000040fe14 and continues incrementing)
Doing a suspend to ram and resume makes the cursor show correctly and error
message not appearing anymore in kernel log.
Software versions:
linux-3.7-rc5, linux-3.7-rc6
xorg-server-1.13.0
xf86-video-nouveau-1.0.4
libdrm-2.4.40
mesa-9.0
It was also the case with xorg-server-1.12.2, xf86-video-nouveau GIT snapshot
from march 2012, libdrm-2.4.33, mesa-8.0.3) but did not happen with this setup
with older kernel (linux-3.5.x, not sure anymore about linux-3.6.x)</pre>
