I have noticed the following recovery a couple of times on my setup when the board was
just sitting for a long time with just pings
It starts with a firmware recovery started from the interrupt handler but the recovery fails
leaving the sdio stuck.
At this stage the only way to get out of it is unload/load of the driver modules.
Have you seen this on your side as well?
