system randomly freezes for few minutes

[Wilfried van Hulzen]

At unpredictable times, not related to load or activity and therefore untraceable to a package, the system completely freezes. This results in screen freeze, seeminly not responsing to keyboard or mouse, unavailability of shares for samba client. Recently I discovered that after (very approximately) 5 minutes the system becomes available again, showing a backtrace in /var/log/messages, log fragments are attached to the problem report.
Recently upgraded from release 7.10 to 8.10. Problem existed in 7.10 already, still exists in 8.10.

Hi Wilfried,

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/lucid.

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 311248

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.
