Public bug reported:
After upgrade to 4.4.0-109, the system won't boot any more.
At the first boot tentative, the following message is shown and the system
freezes:
"Failure reading sector 0xbbcfd0 from hd0"
Upon retry, a kernel panic is shown (see attached screen hard copy)
Going back to 4.4.0-104.127-generic solved the problem.
I've been able to reproduce this bug in a consistent way: I tried
several times to go boot into 4.0.0-109 and the system froze with the
described behaviour, but booting into 4.0.0-104 always worked.
I have checked the bug reports concerning kernel panic after upgrade to
4.4.0-108, but this problem seems to be different: I experience this
problem after upgrading to 4.4.0-109, which presumably fixed the problem
reported the other bug reports (I don't know if my configuration
would've worked with 108, because I have not updated during a week)
