Juan, meanwhile I noted that I have a potential hardware problem (Mainboard or RAM) which added confusion:
Strangely, my system works with one DDR2 module of 2GB but crashes when using two modules. The RAM itself seems ok (tried each of the four modules separately tried every memory bank). While this could be induced by a problem on the mainboard and/or power supply it is still confusing that the problem occured exactly when upgrading to 14.04. Anyways: Currently, with one 2GB DIMM in use I have a probably working setup: kernel 3.13.0-27 xserver-xorg-video-nouveau 1:1.0.10+git1405261930.4a18dd~gd~t libdrm-nouveau2:amd64 2.4.54+git1405200630.8fc62c~gd~t nouveau-firmware 20091212-0ubuntu1 graphics devices drivers are from oibaf ppa Best regards, Sven -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1097178 Title: nouveau failed to idle channel 0xcccc0000 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-quantal/+bug/1097178/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
