I just received my Pandaboard ES (rev B) and I am having trouble after installing ubuntu-omap4-addons.

Once I copied the image ubuntu-12.04-preinstalled-desktop-armhf+omap4.img on my sd card and boot the pandaboard with it, I run the following commands:

sudo add-apt-repository ppa:tiomap-dev/release
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install ubuntu-omap4-extras

At the end of the installation of ubuntu-omap4-extras, Ubuntu tells me that a problem occurs when the console displays:

ldconfig deferred processing now taking place

Clicking on "report the problem" tell me that the problem concerns pvr-omap4-dkms. I read somewhere that this can happen and it is better to reinstall pvr-omap4-dkms. Which I am doing by running:

sudo apt-get install --reinstall pvr-omap4-dkms

I reboot.

Then the board has sometimes difficulties to start Ubuntu: it freezes during the loading page, only action I can do is unplugging the board to start it again. Some other times, Ubuntu load successfully but then freeze at another random time, in the range 20 - 40 minutes.

I searched on internet for similar bug and found this: https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4/+bug/971091

So I typed this in:

update-rc.d ondemand disable
apt-get -y install cpufrequtils
echo 'ENABLE="true"
GOVERNOR="performance"
MAX_SPEED="0"
MIN_SPEED="0"' > /etc/default/cpufrequtils
cpufreq-set -r -g performance
reboot

But it doesn't seems to fix the bug.

Another detail: on startup, before the loading screen of Ubuntu (when there is the two penguins displayed :)), it shows this:

[0.297271] CPU1: Unknown IPI message 0x1
[0.308990] omap_hwmod: mcpdm: _wait_target_ready error: -16
[0.354705] omap_mux_get_by_name: Could not find signal uart1_cts.uart1_cts

[2.107299] stm_fw: vendor driver stm_ti1.0 registered
[8.725555] OMAPRPC: Registration of OMAPRPC rpmsg service returned 0! debug=0

Any idea what can be wrong? I am not that good with Ubuntu so any help will be appreciated.

Cheers!
