John Anderson, 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-rc5 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. ** Changed in: linux (Ubuntu) Status: Won't Fix => 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/1003046 Title: [Lenovo IdeaCentre B320] All my USB devices randomly stop responding Status in “linux” package in Ubuntu: Incomplete Bug description: This is in the dmesg/kern.log right after they all disappear: May 21 13:45:23 booth01 kernel: [157901.125687] ehci_hcd 0000:00:1d.0: fatal error May 21 13:45:23 booth01 kernel: [157901.129569] ehci_hcd 0000:00:1d.0: HC died; cleaning up May 21 13:45:23 booth01 kernel: [157901.132414] ehci_hcd 0000:00:1d.0: force halt; handshake ffffc9000064a024 00004000 00004000 -> -110 May 21 13:45:23 booth01 kernel: [157901.132417] ehci_hcd 0000:00:1d.0: HC died; cleaning up May 21 13:45:23 booth01 kernel: [157901.132429] hub 2-1:1.0: hub_port_status failed (err = -108) May 21 13:45:23 booth01 kernel: [157901.132437] usb 2-1: USB disconnect, device number 2 May 21 13:45:23 booth01 kernel: [157901.132440] usb 2-1.3: USB disconnect, device number 3 May 21 13:45:23 booth01 kernel: [157901.238681] usb 2-1.4: USB disconnect, device number 4 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-image-3.2.0-24-generic 3.2.0-24.38 ProcVersionSignature: Ubuntu 3.2.0-24.38-generic 3.2.16 Uname: Linux 3.2.0-24-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
