[Bug 50757] Re: uhci_hcd generates flood of kernel messages while failing to mount usb stick
Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug does not meet the criteria for a stable release update and is being marked as Won't Fix for this particular version of the kernel. You can learn more about the stable release update process at https://wiki.ubuntu.com/StableReleaseUpdates . However, the issue that you reported is one that should be possible to test with the live environment of the Desktop CD of the development release - Gutsy Gibbon. It would help us greatly if you could test with it so we can work on getting it fixed in the actively developed kernel. You can find out more about the development release at http://www.ubuntu.com/testing/ . If you do decide to test with the development release of Ubuntu please comment on this bug report and include at least the minimal information requested at http://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks again and we appreciate your help. ** Changed in: linux-source-2.6.20 (Ubuntu) Importance: Undecided => Medium Assignee: Ubuntu Kernel Team => Brian Murray Status: Confirmed => Won't Fix -- uhci_hcd generates flood of kernel messages while failing to mount usb stick https://bugs.launchpad.net/bugs/50757 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi. For the moment, move the bug, the Kernel guys can create another one if they need to later. We've noted here that the problem exists in both.

[Bug 50757] Re: uhci_hcd generates flood of kernel messages while failing to mount usb stick
Hi Johnathon, removing the ehci_hcd module doesn't do anything (it wasn't loaded at the time, as shown in the lsmod output). I've tried to load and remove it again, which doesn't change anything. The sole troublemaker seems to be the uhci_hcd module. I remember having read something about the kernel being a bit picky regarding the order in which usb modules are loaded. My /etc/modules lists "usb-storage", then "sd_mod", but neither is there a /dev/sd* device, nor does "sudo lsusb -v" show anything beside the hub after the modules are loaded and the stick is plugged in.

Hi, I've done everything and bundled it up in the attached tar file.

You can learn more about the stable release update process at https://wiki.ubuntu.com/StableReleaseUpdates . However, the issue that you reported is one that should be possible to test with the live environment of the Desktop CD of the development release - Gutsy Gibbon.

[Bug 50757] Re: uhci_hcd generates flood of kernel messages while failing to mount usb stick
Hi Johnathon, removing the ehci_hcd module doesn't do anything (it wasn't loaded at the time, as shown in the lsmod output). I've tried to load and remove it again, which doesn't change anything. The sole troublemaker seems to be the uhci_hcd module. I remember having read something about the kernel being a bit picky regarding the order in which usb modules are loaded. My /etc/modules lists "usb-storage", then "sd_mod", but neither is there a /dev/sd* device, nor does "sudo lsusb -v" show anything beside the hub after the modules are loaded and the stick is plugged in.

Hi. For the moment, move the bug, the Kernel guys can create another one if they need to later. We've noted here that the problem exists in both.

[Bug 50757] Re: uhci_hcd generates flood of kernel messages while failing to mount usb stick
Hi Johnathon, removing the ehci_hcd module doesn't do anything (it wasn't loaded at the time, as shown in the lsmod output). I've tried to load and remove it again, which doesn't change anything. The sole troublemaker seems to be the uhci_hcd module. I remember having read something about the kernel being a bit picky regarding the order in which usb modules are loaded. My /etc/modules lists "usb-storage", then "sd_mod", but neither is there a /dev/sd* device, nor does "sudo lsusb -v" show anything beside the hub after the modules are loaded and the stick is plugged in.
