I suspect that these CONFIG_PROVE_LOCKING=y issues are actually not
kernel issues directly, but kernel size limitations based on the load
addresses used in lab-collabora LAVA.

Comparing against my lab, I'm using load address: 0x42000000 where as
lab-collabora is using 0x41000000. I'm wondering if that is not enough
room to ucompress down to the default boot address without overwriting itself?

I suspect the same problem in the lab-collabora panda boots since the
load address differes from mine in the same way.

@Sjoerd: can someone in lab-collabora maybe have a closer look?

Kevin
