## Reference Platform Build - 15.12 Release - Known Issues

### Enterprise

#### Kernel

- "Bug 1966":https://bugs.linaro.org/show_bug.cgi?id=1966 - KVM errors when booting on overdrive and d02

#### HiSilicon D02

- "Bug 1965":https://bugs.linaro.org/show_bug.cgi?id=1965 - D02: kernel unable to find valid mac for the network interfaces
- "Bug 1967":https://bugs.linaro.org/show_bug.cgi?id=1967 - D02: unhandled level 3 permission fault (11)
- "Bug 1975":https://bugs.linaro.org/show_bug.cgi?id=1975 - D02: Kernel can only see 2GB of memory (from 8GB)
- *SATA*: Due to bugs in the SATA controller, there is a risk of disk corruption when installing to a SATA disk. This is expected to be fixed in subsequent silicon revisions.
- *SAS*: not yet supported in EDK2. For it to work on linux only, this "patch":https://git.linaro.org/uefi/OpenPlatformPkg.git/commit/96d58c4318584f066b1bb7f1c48b72e7e25cf709 needs to be reverted on UEFI/EDK2, but then an alternative boot method needs to be used (since UEFI/EDK2 is unable to load grub/kernel from SAS).

#### AMD Overdrive

#### DragonBoard 410c

- Freedreno graphics driver not provided by the image
   - Newer mesa, libdrm and freedreno xorg driver is needed (work in progress to be included by default as part of the next release)
   - Workaround is to enable the qcom overlay PPA, and install the required packages:

```shell
sudo su -
echo "deb http://repo.linaro.org/ubuntu/qcom-overlay jessie main" > /etc/apt/sources.list.d/qcom-overlay-repo.list
apt-get update
apt-get install libdrm2 libdrm-freedreno1 libegl1-mesa libegl1-mesa-drivers libgbm1 libgl1-mesa-dri libgl1-mesa-glx libglapi-mesa libgles1-mesa libgles2-mesa libosmesa6 libwayland-egl1-mesa libxatracker2 xserver-xorg-video-freedreno
reboot
```
