Hi Folks,
Tried a build of -CURRENT yesterday (28/29th Dec), and had the following
crash on a Beaglebone White.
Thought it might be clocks not enabled for the extra serial ports, as
I had a similar crash when I forgot to enable them before, so applied
my (old) patch, but still the same, so wasn't that.
Did an svn update today (Dec 30th, revision 260082), and while I've
not rebuilt the kernel yet, didn't see any changes in the arm tree
anyway, so suspect the problem remains.
I'm not great with the debugger, but if anyone wants extra info
from it, just let me know which commands to type.
Output from fdt_start to the crash is below.
Iain
