Hi ar,

Can you comment how reproducible this issue is or how often it re-occurs? Could you try running the latest upstream vanilla kernel and see if you can reproduce? https://wiki.ubuntu.com/KernelMainlineBuilds . I'd suggest trying the 2.6.30-rc7 kernel as of this posting. Thanks.

As far as I know, running 2.6.30-rc6, I did not see this error. Upgrading from 2.6.28 to 2.6.30 fixed the error. A lot of errors.
But I do not see every error anymore...

Comment 3 from ar (the original bug reporter) notes this seems to be resolved with the newer 2.6.30 kernel. The kernel for the upcoming Karmic 9.10 release will actually target the 2.6.31 kernel so I would not expect for this issue to regress. For now I'm closing this bug.

@tdn, please try the newer 2.6.31 based kernel either by using one of the latest Mainline kernel builds - https://wiki.ubuntu.com/KernelTeam/MainlineBuilds or ISO CD images of the latest Karmic Alpha releases are available from http://cdimage.ubuntu.com/releases/ . Thanks.
