For example, on a Core i7-920 everything worked out of the box (as did with previous releases), but on a newer Core i5-2300 this bug showed up, no matter how many times the OS was rebooted, services restarted, etc (so the stack space was at different locations). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It doesn't seem to be important to anyone that a default installation even with all updates still breaks. So many users of openSuSE doing their first steps with xen will run into an endless search before they possibly find the above patch. Good user impression - really. Is there something wrong with the patch above or why it is not placed in the update repository? Maybe there should be an extra state in bugzilla for 'rolled out' with an assigned maintainer.

Additional Question: when a bug has come so far, that it is in a maintenance repository - what is usually done with it and how long does it usually take it to enter the official update repository?

I dont have the details for that. Perhaps asking on some of the opensuse mailing lists (factory?) can clearify the process. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
