Fedora 12 kernel Oops gphoto2 debug output
I'm seeing exactly the same problem. However, the problem seems to only occur on one of my F12 machines. I'll try to come up with some more info later. This looks like it might have something to do with our problem: http://bugzilla.kernel.org/show_bug.cgi?id=14564 For anyone still affected by this issue, or any Googlers' stumbling on this, I have found a workaround just in case it helps. This device supports USB 2.0 (Canon PowerShot S2 IS). However, there seems to be an issue with the way ehci is interacting with the device which then causes the crash. Since now USB modules are compiled into the Kernel, I didn't find an easy way to disable ehci (without going through the hassle of compiling a Kernel from scratch) or an easy way (which works) to force only this particular USB device to use uhci (USB 1.0). Instead, I simply plugged the device to a USB 1.0 HUB (i.e. an older hub which doesn't support usb 2.0) and that did the trick. The Camera snapped 1,000,000 images since then without the issue manifesting itself. Crude workaround (i know) but one which seems to work nonetheless. If you try this out, make sure to check your system log. You should see the camera is connecting through uhci_hcd as oppose to ehci_hcd. This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
