Hi All,

I am working on custom i.MX6 quad hardware and using RT patches for
almost latest stable kernel 4.9 and facing some weird system stall OR
'unhandled page fault - exceptions'.

I'm not sure about the unhandled page fault, but the stalls may be
because of the SDMA driver.

See this patch in the Freescale/NXP community for kernel 4.1:
https://github.com/Freescale/meta-freescale/blob/master/recipes-kernel/linux/linux-fslc-imx-rt/0003-Work-around-CPU-stalls-in-the-imx-sdma-driver.patch

Thanks for the patch link. I will give it a try.

Regards,


Eric
