umount caused kernel oops after suspend/resume with encrypted SD card

[Rob David]

I have an HP nx8220 laptop with a built in SD card slot. Suspending and resuming the laptop with a mounted encrypted SD card resulted in a kernel oops:

I can't recall the exact sequence of events, but I believe it was:

* Inserted SD card. Prompted for passphrase. Entered and selected "remember passphrase forever"
* Icon for SD card appeared on desktop with open padlock icon. Successfully accessed files.
* Suspended and resumed laptop.
* Was prompted again for passphrase for SD card. Again entered and selected "remember passphrase forever"
* Got an error message dialog saying something to the effect that the file system was already mounted.
* Icon for SD card appeared on desktop *without* padlock icon.
* Right clicked on SD card icon and unmounted the drive.

Hi Rob,

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? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 546316

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. 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. Please let us know your results.

Thanks in advance.

OK, I've tried my scenario again with the latest updates installed. I now have kernel 2.6.32-21-generic. I'm still able to induce a kernel panic, although It doesn't seem to happen every time.

I'm using an SD card that is encrypted (using luks) and I've got Gnome to permanently remember the encryption key, so I can just insert the card without having to type the password. So, my sequence of events is:

* Insert SD card. The icon for the card appears on the desktop and I can access it fine.
* Suspend and then resume the laptop. At this point the dialog asking for the encryption password pops up. This shouldn't happen as Gnome should be remembering the encryption key.
* Enter the password and click "connect". I then get a popup saying that the luks device in /dev/mapper already exists.
* Click OK to cancel the popup. At this point there is stil an icon for the SD card on the desktop. It still seems to be a functional mount point, and I can still browse files on it.
* Right click and unmount the card. This is the point that a kernel panic might occur (pasted below).

In any case, there is a luks device left in /dev/mapper, and the only way I could get rid of it is by doing a "dmsetup remove".

I had to repeat the cycle about three times before I eventually oopsed the kernel.

I've tried to test this issue with two mainline kernels: 2.6.33-02063302 and 2.6.34-020634rc6, but suspend and resume was non-functional with both of these, so I wasn't able to.

[Likewise (leonw)]

I have a similar issue as the reporter. I was trying to insert an SD card into my monitor, I was fiddling a bit finding for correct insertion. SD Card showed up in Nautilus and I was looking into "dmesg" to see what "sdX" device it had gotten. Then I saw the WARNING.

Rob David, 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 <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 kernel 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-v3.11.1

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.
