Is there any chance to put the workaround/patch into the Linaro omap4
kernel as well?

Since Sebasien Jan took my patch into his tree, and the Ubuntu Panda
kernel is coming via his tree, it should mean that kernel has the patch
in it. You can confirm it with
$ dmesg | grep "6030: Interrupt status"
if it shows anything it's using the patch.

interesting observation...
If I start with linaro-natty-headless image, build kernel mentioned in #39 with
patch applied from #37, the kernel boots fine and the board stays up for hours.
If however I start with linaro-n-developer image, build kernel
mentioned in #39 with patch applied from #37,

Your patch fixes the issue on my board. I've applied your patch to the linaro
natty kernel and the system stays alive.

After a lot of help from kenws testing, I have a small patch which
should stop the Panda going OFF. I can explain why it goes off without
the patch, but since TI won't let me have a twl6030 datasheet I can't
get right to the end yet.
Basically the Panda PMIC is seeing an overcurrent on one of its
For what it's worth, just as Ken reported, the PWRON_RESET button works
just as expected with the hybrid linaro/natty image described above, but
does not do anything when pressed after booting Ken's test image (image
that reproduces the symptoms of this defect).

Thanks for the LED heartbeat hint. I've added ledtrig-heartbeat to /etc/modules

dies (shortly after it gets to the bash prompt on my board) the LED stays off
and the CPU cools down. The board works fine as soon

I added the modprobe ledtrig-heartbeat to /etc/rc.local for now,

Most of this confusion is coming because the LED trigger heartbeat is
being built as a module (why?) and not inserted.
If you type

at the prompt you will get the familiar flashing LED letting you know

@Aneesh... my problem was with USB OTG power of the board, it is fixed

Did your x-loader changes fix the above issue conclusively.
I had seen similar issue(the one that you have explained in your patch not this
bug) on Blaze and fixed it with this patch(On this tree this would also apply
to Panda).

What I still don't understand is why Paul Larson was able to reproduce
this issue without ever touching the USB OTG and using just the external
power supply?
The x-loader that Paul is using is already based on this upstream one,
and it's the same one we're using at the Ubuntu images.

Well, there's no reason to expect it should be consistent since we
didn't compare which version of Xloader and U-Boot I am running and you
already have reason to believe the behaviour depends on that. However
what I reported is repeatable on this board with

That is not consistent with my observations. I have been able to
reproduce this with *nothing* plugged into the board other than the
external 5V4A power - not even usb for serial. The board shuts down and

I was trying to power my Panda board from USB OTG connector, it dies
early in boot apparently in xloader or u-boot when connected to a
laptop.
I did three tests
1) Short the USB OTG 5V pin to the DC Jack 5V pin in case something in
the OTG 5V path makes trouble. It still dies in early boot.
2)

This kernel works fine for me when installing it at the Ubuntu Natty

Seems I'm using a newer u-boot, so it would be good to test to make sure
it's not related with it.

I've tried various hwpacks and (headless) images and encountered exact

Confirmed I still see this problem with 20110201-1 image, BUT, I do not
see this problem when booting in the validation lab with old

problem with xloader or uboot.
