Shutdown Fails To Complete

[Vaughan Butler]

Have just upgraded from 9.04 to 9.10, which went pretty smoothly apart from the process hanging at the final restart request. After a power off/on the new version came up OK and AFAIK all is well. However on shutdown, this hangs at a text screen - after the instruction *Deactivating swap... I get the message [6592.716216] Buffer I/O error on Device Loop0, Logical Block 1573453.

This has happened on every shutdown so far, and waiting for the shutdown to complete produces no further activity. The figures quoted in the message seem to vary, and on one occasion there were multiple messages, some with different figures.

Whether this will help or not.... I think i should share

Problem at shutdown failure at deactivating Swap.... Solved on Karmic Ubuntu

After over a month, desperately searching the INTERNET launchpad and wherever the search engines took me. I found the solution for my system. It is so simple I'm surprised none of the experts of the many many forums ever suggested it.

I forced my system off, i restarted to bios and power it off from there, tried to modify scripts and power down using various commands, yet it all failed, the hours & hours wasted. After almost giving up & waiting for the next major update to Lucid Lynx meaning months to shutdown my system properly (silly but well what can i say)

OK to the point.... which really really doesn't make me happy.... because of its simplicity.

I decided to find some shutdown tools in the hope that an advanced tool might help... So I Entered Synaptic Package Manager

Did a search... typed shut (& of course the results had a few tools for shutting down) or you can search initscripts which is my solution

1. I right clicked (sweet no command line)
2. Mark for re-installation (sweet so simple)
3. Apply & let the task complete

4. Reboot / perhaps shutdown & your computer powers off itself (You must love technology that turns off when you tell it to)

As a new user, why of why didn't anyone say i could have reinstalled that, i was thinking how to reinstall shutdown but didn't know the term i needed. I'd be interested to know, does this solve a

Hi Vaughan,

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 464496

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.
