Help: System freeze when edge interrupt trigger, Xenomain3.0.8, ipipe-arm main line, am335x

[张建昆]

Hello!
    The system freeze when interrupt is triggered. I clone ipipe-arm master, and use xenomai 3.0.8 following xenomai startup tutorial.
The hardware cpu is am3358. System works fine after start up, but the system immediately locks up when a edge interrupt. For example,
the mmc card in pluged in. Is it something worng ? Thank you very much!

    The kernel config file and dts attached.

Have you tried this with the 4.9 or 4.4 kernel and ipipe patch?  I
think 4.4 (which is based on a SLTS) has been tested on beaglebone
(similar processor). Did you mean kernel 4.14 not 3.14?

I think I've reproduced this on a Beaglebone which is based on a
similar processor, I'll look into it this week.
