Hi,

Observing kernel oops on Power9(ZZ) box, running on PowerVM, while 
running stress-ng.


Kernel: 4.18.0-rc4
Machine: Power9 ZZ (PowerVM)
Test: Stress-ng

Attached is .config file

Traces:

  [12251.245209] Oops: Kernel access of bad area, sig: 11 [#1]

Can you post the lines above this? Otherwise we don't know what address
it tried to access (without decoding the instructions and reconstructing
it from registers at least, which the XFS devs wouldn't be inclined to
do).

And I assume there is nothing else relevant to XFS in the dmesg before
this?

Thanks,
Nick
