i915: 3.1.0-rc3+: WARNING: at fs/sysfs/dir.c:455 sysfs_add_one+0xb8/0xf0()
by Sergei Trofimovich 27 Aug '11

27 Aug '11

Around -rc2+ i've noticed the following warning in dmesg [1] > WARNING: at fs/sysfs/dir.c:455 sysfs_add_one+0xb8/0xf0() > sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/intel_backlight' It tries to register backlight twice, so fails miserably. The machine is compaq-2510p with 965GM. Reverting commit aaa6fd2a004147bf32fce05720938236de3361d9 helps. ("Not all systems expose a firmware or platform mechanism for changing the backlight intensity on i915, so add native driver support.") Attached dmesg before reverting the patch and after. Thanks!

[Bug 27314] displayport link training fails on certain panels (channel equalization fails)

https://bugs.freedesktop.org/show_bug.cgi?id=27314 --- Comment #54 from Merlijn Wajer <merlijn(a)wajer.org> 2011-08-27 06:10:09 PDT --- I can confirm DisplayPort seems to work for me as well now with Linux 3.1-rc3. It didn't work on previous kernels (I'm not sure if I tested 3.0, but certainly not before 3.0) when using my Dell U2133H monitor. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
