[Linaro-validation] Interesting(?) health failure

Hi all,

I found an interesting health failure today on origen07

http://validation.linaro.org/lava-server/scheduler/job/35016/log_file

When you look at the log, you see that the board starts off at the u-boot prompt. It then tries to do a "reboot", which (obviously) fails. So naturally, it then does a hard reset, and this is where it does something very odd: It interrupts the boot and tries to boot the previously installed test image. I haven't yet looked at the dispatcher code to figure out why (that's my next job).

What then started alarm bells ringing was that I saw this:

1261680 bytes read reading uInitrd

1532597 bytes read reading board.dtb

** Unable to read "board.dtb" from mmc 0:5 **

So whatever the test image was, it was expecting a device tree blob, which I would have assumed would have to have been installed during deploy_linaro_image() being that if there is one it should just be part of the test boot deployment.

So I looked at the log from the previous job:

http://validation.linaro.org/lava-server/scheduler/job/34938/log_file#entry2...

and sure enough, you'll see at that mark the same issue.

So there are two things:

1) There's some twisted logic in the dispatcher that's making it do odd things if it starts off in u-boot 2) Do we have an issue with dtbs not being handled properly by lava, or is it just that the hwpack was incomplete?

Thanks

Dave
