Package: src:linux
Version: 4.2.3-2
Severity: normal

Running the Tails test suite[0] (which involves starting virtual machines
using KVM) my system is oopsing. The screen locks up when the kernel
oopses.  The system itself is not locked since I can log in remotely.

I can reliably reproduce this problem when booting a KVM virtual machine
in UEFI mode. During this portion of the Tails test suite the following
will be logged:

As mentioned earlier, the oops can be consistently triggered. I have been able to
reproduce this bug with the Debian package I'm filing this bug against as well
as self-compiled kernels of 4.2, 4.2.3, and 4.2.4. After many runs and
reboots I've managed to hit the oops every single time.

After many, many tries, I *cannot* reproduce the oops with a self-compiled 4.1.11 (git revision
205a851).

Please let me know if I can provide more information or when there are
patches that you'd like me to try.

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
