Re: Why is my syslog filling up with 'wakeup int at ci_hdrc.1' 'ci_hdrc ci_hdrc.1: at ci_controller_resume' 'ci_hdrc ci_hdrc.1: at ci_runtime_suspend' ?

I tried booting a few older kernels.  I finally found one that didn’t do this: 3.16.0-4-armmp,  which is pretty old.

So, did something happen between kernels 3.16 and 4.1.

Googling for ‘wakeup int at ci_hdrc.1’ (or one of the other repeated strings) gets me to a discussion from January, 2015 timeframe on the linux-usb mailing list about (I think — I’m not a USB driver expert!) some proposed patches to workaround a bug in the chipidea USB controller.  Is this a clue?

For the time being, I guess I’ll be sticking with the 3.16 kernel for a while.

Any help will be appreciated…

Thanks!
