Status changed to 'Confirmed' because the bug affects multiple users.

[Stefan Bader (smb)]

This is a limited re-spin which is mostly concerned about boot testing. The ADT results show a bunch of GOOD which involves booting, so it is save to assume that any issues showing are just the usual test case problems.

[Stefan Bader (smb)]

Sorry should have been set sooner. This is a respin for limited security related changes. Full cert is not needed.

[Stefan Bader (smb)]

This was a security respin. Boot test results obtained via ADT.

This looks to be ready to go.
