A bug report about the Xen timer issues that were mostly Ubuntu-related.
It’s been opened in 2007, has multiple loops of “are you sure this still broken?” “yes it still is” “for me too” and of course not a single developer working on it, aside from informational messages like
“The Ubuntu kernel team is no longer assigned bugs as per decision of the Ubuntu kernel team” and the glorious “this bug was filed against a now unsupported release and will now be closed as wontfix”. As a cherry on top this is right after someone verifying the issue still exists in 2011.
A special price for readers who notice the posting of the guy who actually traced down the problem and goes unheard.
