If the problem is solved, change the tag 'verification-needed- eoan' to 'verification-done-eoan'. If the problem still exists, change the tag 'verification-needed-eoan' to 'verification-failed-eoan'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

[Regression Potential] * Regression potential should be low, as we're now updating the VSI using the ID stored in the VF pointer * Regressions could arise from issues in VF creation or reset, as that would corrupt the new VSI pointer * Patch was validated and tested in a production environment To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1852432/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
