[Bug 888828] Re: sysfs: cannot create duplicate filename '/class/bluetooth/hci0:1 2'
James M. Leddy, 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 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 ** Tags added: bios-outdated-1.40 ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Summary changed: - sysfs: cannot create duplicate filename '/class/bluetooth/hci0:1 2' + [ThinkPad X201s] sysfs: cannot create duplicate filename '/class/bluetooth/hci0:1 2' ** Summary changed: - [ThinkPad X201s] sysfs: cannot create duplicate filename '/class/bluetooth/hci0:1 2' + 0a5c:217f [ThinkPad X201s] sysfs: cannot create duplicate filename '/class/bluetooth/hci0:1 2' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/28 Title: 0a5c:217f [ThinkPad X201s] sysfs: cannot create duplicate filename '/class/bluetooth/hci0:1 2' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/28/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 888828] Re: sysfs: cannot create duplicate filename '/class/bluetooth/hci0:1 2'
Just had this problem again, even with latest raring kernel (3.8.0-19). I think this problem is related to the power info of HID devices.

Hey folks, we're still seeing this on Chrome OS. We have a 100% reliable repro case: - have Apple Magic Trackpad connected and working - sleep/wake - immediately click/rub fingers on trackpad - panic! We're tracking this at https://code.google.com/p/chromium/issues/detail?id=228937 We're planning to put in the hack listed, since it works for us, but we would like to let others know that, as far as we can see, this issue persists. If there is a fix not linked from here, we're eager to find it! We are using the 3.8 bluetooth stack with a 3.4 kernel. ** Bug watch added: code.google.com/p/chromium/issues #228937 http://code.google.com/p/chromium/issues/detail?id=228937 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/28 Title: sysfs: cannot create duplicate filename '/class/bluetooth/hci0:1 2' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/28/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Okay, I may be able to reliably reproduce this by rapidly turning on and off the kill switch while moving the mouse. I just had it happen again and now my mouse doesn't work at all.

This was a one time event. I was hoping that someone would be able to find the bug based on the traceback based on it being a WARN leading to a null pointer. I don't have a consistent reproducer, but I expect this to be a bug upstream unless someone else had fixed it. If it happens again I'll let you know and install mainline. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/28 Title: sysfs: cannot create duplicate filename '/class/bluetooth/hci0:1 2' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/28/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 888828] Re: sysfs: cannot create duplicate filename '/class/bluetooth/hci0:1 2'
Was this a one time event, or can you reproduce this? Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . If possible, please test the latest v3.2-rcN kernel (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the others). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.2-rc1 fixed and issue, the tag would be: 'kernel-fixed- upstream-v3.2-rc1'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.
