I do not want to miss something that may be important. The difference I see in linux 3.2.0-38 and later kernels is the error happening in a loop in the later versions.
I do not use the desktop. I boot to the console and then startx. I do not need the desktop and often run without X. An additional note, the error message is presented on all kernel versions I have tested. However, with ubuntu 12.04 and linux 3.2.0-38-generic, the message is presented one time and then stops when the console login prompt is presented. With all later versions of the kernel, the error message is presented in a loop and makes the machine performance very sluggish, slinky scrolling, etc. The following combination presents the error message one time and then stops. > lsb_release -a LSB Version: core-2.0-amd64:core-2.0-noarch:core-3.0-amd64:core-3.0-noarch:core-3.1-amd64:core-3.1-noarch:core-3.2-amd64:core-3.2-noarch:core-4.0-amd64:core-4.0-noarch Distributor ID: Ubuntu Description: Ubuntu 12.04.2 LTS Release: 12.04 Codename: precise > uname -a Linux P9X79 3.2.0-38-generic #61-Ubuntu SMP Tue Feb 19 12:18:21 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Tom Dean -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1151622 Title: [ASUS P9X79 PRO] The usb driver appears to fail To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1151622/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
