Comment 9 for bug 1274479

One information that I missed adding is before I saw Call trace i.e around 5 -1 01 min before it I had run stressapptest .

I found the below message in dmesg after stressapptest
stressapptest[6384]: unhandled signal 11 at 000000fe27f0f438 nip 0000000010014440 lr 0000000010014424 code 30001

ran : zzuf stressapptest -s 20 100
and fsracer tests was in background.
