Comment 75 for bug 22070

I'm going to build you another set of kernels.

Once you've installed then ensure you issue this command before you run your tests again.

echo 7 7 7 7 | sudo tee -a /proc/sys/kernel/printk

That will allow all of the debug prints to be reflected in the logs.

Give it another 30 mins or so (or check make sure all the time stamps are up to date) and re download your kernels.

Thanks for your help. :)
