Hi there,
When booting linaro snapshots on my PandaBoard the system hangs a few seconds after the bash prompt is shown (sometimes a little earlier). My first step was to enable magic-sysrq but the system doesn't react on them. It looks like it's already powered off - very strange. I've tried various hwpacks and headless images and also an SD-card image that works works on a pandaboard of a colleague (20110127 hwpack with 20110126 headless) but everything fails with the same symptoms. I used two different power supplies and several SD cards - also no difference. The board itself doesn't seem to be defective as the ubuntu-netbook-10.10-preinstalled-netbook-armel+omap4.img runs flawlessly for hours. I replaced the 2.6.35 omap4 kernel of the ubuntu 10.10 image with a kernel built from the latest git://git.linaro.org/ubuntu/linux-linaro- natty.git - but then the board hangs again. Attached is the output of the serial console. Any hints/suggestions on how to get the linaro kernel working on this board are much appreciated.
Regards Ken
Hi Ken,
FWIW I'm running fairly recent linaro images on my pandaboard with success.
hwpack in my case was from 0119.
Your boot log looks pretty much like mine does, warnings and all.
Regards, Tom

Hi Tom,
Thanks for the info. First I thought I might have to do with the image creation process (different l-m-c versions for example). So I asked Dave Gilbert to sent me an SD card image that works on his PandaBoard. It's really strange but it shows the same behaviour on my board as the images I created myself. This could indicated that my board has issues. But on the other side the Ubuntu 10.10 system is running fine. There is one thing I noticed when the board "hangs" and doesn't react on anything: It seems that the temperature of the CPU/Memory is getting down quite fast and two LEDs are off. Maybe it's powered off already?
Regards Ken

This sounds like https://bugs.launchpad.net/ubuntu/+source/linux-linaro/+bug/708883 to me.
I have no idea what's going on.

Thanks for the pointer - the symptoms are matching. I've disabled watchdog and and USB support from the kernel but the board still hangs.

I am now seeing the exact same thing on my Panda with alip 20110201-2 and other images.
I have seen similar problems when running Ubuntu netbook 10.10. Initially it boots fine but Ethernet is very random on whether it will work or not. Repeated attempts to connect eventually work, and when it does, it is reliable. However, after installing all the packages for setting up a dev environment, the board will hang exactly the same. A reboot is required after the packages are installed, then it hangs. I was able to get the message "X-Loader hangs" at the last attempt.

Hi All,
Is there any fix to these issues with Panda.
Thanks Sachin
