Comment 1 for bug 2025537

Were you using the generic kernel stack ? If yes, check your kernel release number (uname -r) to confirm it’s still the generic kernel (should end with “-generic”).

If your kernel stack suddenly changed, you’re not alone. People have reported the updates going fancy and installing unwanted kernel stacks. I hope this won’t get unnoticed by Canonical for too long, as it could have severe availability consequences for some people.
