Ah shucks, pstore isn't big enough to dump the ftrace buffer; and is too slow in writing out the data that it causes the NMI watchdog to fire.
Rising priority since it is BAT.
I dup this on bug 103706 since I have all the other ftrace/pstore anomalies there *** This bug has been marked as a duplicate of bug 103706 ***
