USB Memory Stick is remounted every 10 seconds

Thanks for your bug. Could you follow the instruction of https://wiki.ubuntu.com/DebuggingRemovableDevices to get a log of what is happening?

I followed the instructions in the wiki. All files include one "remount", except the dmesg-output, it includes more than one remount.

thanks. I'll leave it unconfirmed while someone with more knowledge takes a look at your output.

I tried the same configuration. With a Kingston pendrive and had no problem in a Edgy Eft LiveCD.

Did you use some other configuration?

I think the problem could see bad blocks on your Pendrive. Did you try to reformat it?

This looks like either a kernel or a hardware bug:

Is it possible that this might be a power surge or temporary disconnect due to a bad cable or connector? Do you get similar problems with another stick? Or with the same stick on a different computer?

Please look in my first posting:
Using the same Stick/Cable/Port with installed Dapper works fine.
My Digital Camera is recognized by Edgy as expected: No remounts.

So for me it seems to be a Software problem with Edgy, which occures with this USB-Stick.

This is probably fairly obvious, but have you tried it on another USB port on that computer? I've marked this as confirmed, so hopefully someone more knowledgable with this type of issue will see it and take a look.

Hi Guys,

Just moving this bug forward to the Hardy "linux" kernel package since the 2.6.17 for Edgy has reached it's end of life for the 18 month support period. When you get a chance, please confirm this against Hardy. Thanks.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Unfortunately this bug report is being closed because we received no response to the last inquiry for information. However, the Intrepid Ibex 8.10 Beta release was most recently announced - http://www.ubuntu.com/testing/intrepid/beta . If you are able to confirm this is still an issue with this most recent release please feel free to reopen this report. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to "New".

Thanks,
Markus

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? May you please try the same with Karmic? Thanks in advance.

We are closing this bug report because it lacks the information we need to investigate the problem, as described in the previous comments. Please reopen it if you can give us the missing information, and don't hesitate to submit bug reports in the future. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to "New". Thanks again!
