Comment 1 Chris Wilson 2017-11-10 09:58:44 UTC

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.

Comment 2 Elizabeth 2017-11-14 19:55:56 UTC

Rising priority since it is BAT.

Comment 3 Marta Löfstedt 2017-11-16 12:16:14 UTC

I dup this on bug 103706 since I have all the other ftrace/pstore anomalies there

Did the same fix from 103706 worked for this one??

bug 103706 is about CI system infrastructure problems, this bug is just a clean duplicate of that issue.
