Windows 7 guest won't start on Ubuntu host when using kernel 3.11

[Konstigt]

Host system is running Ubuntu 13.04. Upgraded kernel from ​http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11.5-saucy.

When I start my Windows 7 guest, it won't boot. If I reboot to stock kernel 3.8.0 it boots fine.

$ apt-cache policy virtualbox-4.3 virtualbox-4.3:

Installed: 4.3.0-89960~Ubuntu~raring Candidate: 4.3.0-89960~Ubuntu~raring Version table:

Are only 32-bit hosts affected?

[Frank Mehnert]

I cannot reproduce this problem. Using the latest available kernel (3.11.0-13-generic) on a 32-bit host. No problem to start several guests using VBox 4.3.2. Please reopen if still relevant with VBox 4.3.2 and with the latest host updates.

Using VirtualBox 4.3.2.r90405 & Ubuntu 13.10 with kernel 3.11.0-13-generic #20-Ubuntu SMP Wed Oct 23 17:26:33 UTC 2013 i686 i686 i686 GNU/Linux

Definitely still hitting this problem.

I'd be happy to provide any additional info.

Kresimir, please provide a VBox.log file for such a VM session.

[Kresimir Tonkovic]

I just ran an upgrade and now I can start the Win7 VM.

Unfortunately, both the Linux kernel and VirtualBox upgraded, so I can't say which one fixed the problem.

My versions now are: VBox 4.3.4.r91027 Linux kernel: 3.11.0-14-generic

Please reopen if still relevant with a recent VirtualBox release.
