BUG: soft lockup - CPU#0 stuck for 61s! [cupsd:3709]

[falstaff]

I updated to Jaunty when RC was released. Since then I had 3 total freeze. Today I felt like something is wrong and looked in dmesg, which is attached... After several seconds the system freezed again. I think the freezes befor would have the same dmesg entries, but i missed to save them...

I have the same cpu freezing issue, unfortunately it happens (apparently) at random times.

Thanks for testing and confirming against the latest Jaunty released. Please 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-image-2.6.28-11-generic 363368

If the issue remains in Jaunty, if you could also test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine this 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.
