Nobody cared... USB Crash issue

Hi, 

I am working on linux 4.14.62 version for the         i. Mx8 Dx6 board.  The board has USB 2.0 host controller supported by cadence. And the driver is provided by which was originally meant to support cadence 3.0 host controller . The driver is backward compatible with usb 2.0 .

 

Now coming to the issue. The initial code which was running on the board was with several unwanted components so we did a clean up of the code removing the unused drivers and dts entries. And soon after which we started getting kernel warning indicating the usb interrupt is being disabled since it is not handled.

 

This error message is very random when other drivers such as wifi is enabled .

 

So my doubt is whether interrupt handling issue here is something related to timing issue?.. Whether there is any possibility for this?.

 

Anybody can guide on this
