We see this problem on several cm-t3517, but not all of them.
It looks something like:
--------------------cut----------------------------
NET: Registered protocol family 16
GPMC revision 5.0
gpmc: irq-20 could not claim: err -22
OMAP GPIO hardware version 2.5
In-band Error seen by USB_OTG  at address 0
