Comment 0 for bug 1635447

My HP dm3z-2000 laptop works out of box for everything with Ubuntu 16.04, but fails to boot up after upgraded to 16.10. The upgrading went smooth itself.

Laptop still can boot up with the latest 4.4 kernel of 16.04 which I did a regular update/upgrade before 16.10 release upgrade.

Then I tried to boot with 16.10 Live USB and got same result.

It also can boot up with kernel 4.8 if "acpi=off" parameter in place, but it takes long time to boot up. Everything seems fine after logged in.

I couldn't get any log files since the system won't boot up, Ctrl+Alt+F1 does nothing. I can only see some messages in text boot mode, so I took a screen shot with my phone and attached here.

Let me know how to get more details.
