Joe Barnett, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc3 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: needs-full-computer-model ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/714708 Title: logs flood with usb_set_interface failed and ERROR no ro om on ep ring Status in “linux” package in Ubuntu: Incomplete Bug description: I see both of these messages somewhat regularly, but occassionally the kernel will get into some crazy loop where they repeat, eating up CPU and log disk space: Feb 7 07:39:11 taplop kernel: [13394.421661] 4:1:1: usb_set_interface failed Feb 7 07:39:11 taplop kernel: [13394.422350] xhci_hcd 0000:02:00.0: ERROR no ro om on ep ring Feb 7 07:39:11 taplop kernel: [13394.423663] 4:1:1: usb_set_interface failed Feb 7 07:39:11 taplop kernel: [13394.424626] xhci_hcd 0000:02:00.0: ERROR no ro om on ep ring Feb 7 07:39:11 taplop kernel: [13394.425621] 4:1:1: usb_set_interface failed Feb 7 07:39:11 taplop kernel: [13394.426767] xhci_hcd 0000:02:00.0: ERROR no ro om on ep ring Feb 7 07:39:11 taplop kernel: [13394.427697] 4:1:1: usb_set_interface failed Feb 7 07:39:11 taplop kernel: [13394.428754] xhci_hcd 0000:02:00.0: ERROR no ro om on ep ring ProblemType: Bug DistroRelease: Ubuntu 10.10 Package: linux-image-2.6.35-26-generic 2.6.35-26.46 Regression: No Reproducible: No ProcVersionSignature: Ubuntu 2.6.38-2.29-generic 2.6.38-rc3 Uname: Linux 2.6.38-2-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23.
