kernel oops on umount

[coszmos]

When trying to umount an iso loopback filesystem, the kernel does an oops. This leads to an overall system hang. I've attached the oops report.

Linux xxxxxxx 2.6.24-19-generic #1 SMP Wed Aug 20 22:56:21 UTC 2008 i686 GNU/Linux

Intel(R) Pentium(R) 4 CPU 2.80GHz

Steps to try to reproduce:

1. # mount -o loop /home/bcc/ubuntu-8.04-desktop-i386.iso /mnt
2. # sudo -s
3. Try to umount by using tab completion: # umount /m<tab>

Hi coszmos,

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/karmic .

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 274882

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.

I have verified that this no longer happens on this system.

Marking this as fixed based on the previous comment. Thanks!
