John Lindgren, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, 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 following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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-v3.11-rc4 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 If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER 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-kernel-logs needs-upstream-testing regression- potential ** 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/1073688 Title: Kernel crash when unplugging ExpressCard-to-USB adaptor Status in “linux” package in Ubuntu: Incomplete Bug description: This is a somewhat complex problem and seems to be the combination of two separate bugs, one present in 12.04 (kernel 3.2.0-32-generic) and another new in 12.10 (kernel 3.5.0-17-generic). The problem is seen when unplugging an Encore Electronics ENPUH-302 ExpressCard-to-USB adaptor, with a generic USB thumb drive attached, from a 64-bit Intel Atom system. On 12.04, I see this message logged 20 seconds after removing the card: "xhci_hcd 0000:0b:00.0: Timeout while waiting for configure endpoint command". If I plug the card in again during that 20 seconds, it is not recognized (dmesg says only "pciehp 0000:00:1c.3:pcie04: Card present on Slot(35)"). On 12.10, the problem is worse. The same message ("Timeout while waiting ...") is logged 20 seconds after removing the card. If I plug the card in again during that 20 seconds, I see an additional message that was not printed in 12.04: "pciehp 0000:00:1c.3:pcie04: >Device 0000:0b:00.0 already exists at 0000:0b:00, cannot hot-add". If I then unplug the card, the kernel dumps a crash report (a page fault triggered by pci_stop_bus_device()) to the screen and the system freezes. Attached are the following logs: 12.04/dmesg-boot.log: dmesg output when booting system with (Ubuntu 12.04) 12.04/dmesg-insert.log: dmesg output when plugging ExpressCard in-out-in-out (Ubuntu 12.04) 12.04/lspci-out.log: "lspci -tv" output without ExpressCard inserted (Ubuntu 12.04) 12.04/lspci-in.log: "lspci -tv" output with ExpressCard inserted (Ubuntu 12.04) 12.10/dmesg-boot.log: dmesg output when booting system with (Ubuntu 12.10) 12.10/dmesg-insert.log: dmesg output when plugging ExpressCard in-out-in (Ubuntu 12.10) 12.10/lspci-out.log: "lspci -tv" output without ExpressCard inserted (Ubuntu 12.10) 12.10/lspci-in.log: "lspci -tv" output with ExpressCard inserted (Ubuntu 12.10) 12.10/kernel-dump.png: snapshot of monitor showing kernel crash dump (Ubuntu 12.10) The testing system is the following Kontron COM on a custom board: http://us.kontron.com/products/computeronmodules/com+express/com+express+compact/comecpv2.html Let me know if you need any more info.
