Priority: medium Bug ID: 57350 Assignee: dri-devel@lists.freedesktop.org Summary: [nouveau, linux-3.7-rc] Broken cursor and kernel log swamped with "PAGE_NOT_PRESENT" errors Severity: normal Classification: Unclassified OS: All Reporter: bonbons67@internet.lu Hardware: Other Status: NEW Version: XOrg CVS Component: DRM/other Product: DRI
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)
