Ubuntu kernel 3.13.0-85-generic locks with VirtualBox 5.0.14

[Alberto Sentieri]

  affects ubuntu

The kernel 3.13.0-85 locks with Virtual Box 5.0.14. After the lock,
keyboard and mouse are completely unresponsive and screen is frozen. The
problem started with 3.13.0-83-generic, and does not happen with kernel
3.13.0-79-generic.

Unfortunately I was not able to capture dmesg for any of the official
kernel locks, but I was able to capture it for a kernel I compiled
(which uses 3.13.8-83 as its base). The kernel I compiled has minimal
changes to drivers/usb/core/quirks.c, which are necessary for some tests
I do, and uses the exact same configuration file as the official kernel.
Just after booting the kernel I compiled and before doing any tests, I
noticed the strange Virtual Box behavior and was able to capture the
dmesg, which follows. Note, however, that both 3.13.0-83-generic and
3.13.0-85-generic official versions kernels are locking. I am not sure
if the lock is related to Virtual Box. I believe that the lock I saw on
the kernel I compiled has the same cause as the locks on the official
kernels.

Would it be possible for you to test the latest upstream stable kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.13 stable kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.
