Hi all,

I am using P2020 with Linux kernel 3.8.13.
Sometimes my system encounters machine check exception and it shows “Caused by (from MCSR=20000000): Data Cache Push Parity Error”.
Could anyone show me some hints to dig into this issue? Any comment is welcome.
Thanks in advance.

I suggest contacting Freescale support about this
(support@freescale.com) -- I don't think this is the type of error that
you'd normally see from software misbehavior.
