RE: Oops: 17 SMP ARM (v3.16-rc2)

From: Mattis Lorentzon
Date: Thu Jun 26 2014 - 09:16:22 EST

Hi again,

The Oops seems to have been introduced somewhere between v3.12 and v3.13:

- The Oops is reproducible within seconds when running Linux 3.16-rc2.
- We have observed the Oops on 8 different hardware units and two different chipsets (Freescale i.MX6 and Xilinx Zynq).
- The Oops has not been seen on Linux 3.12 so it appears to be good.
- The Oops has been seen on Linux 3.13, 3.14, 3.15, 3.16-rc2 so these appear to be bad.

Configs and a couple of Oops reports are attached.

Best regards,
Mattis Lorentzon
