We have tried to remove the board specific interrupts-extended field and the
MX6QDL_PAD_GPIO_6__ENET_IRQ entry. Sadly this did not seem to improve
the stalls. Our interrupts look like this now:

150:      15519          0          0          0       GIC 150  2188000.ethernet
151:          0          0          0          0       GIC 151  2188000.ethernet

Our device tree might still be slightly incorrect. We have noticed that our
RGMII_INT is connected to GPIO 19 (P5) which might be nonstandard (we are
a bit surprised that this works at all). We are not quite sure how to configure
this properly.

Best regards,
Mattis Lorentzon
