I did the following patch to discard the packet if it was IN_NETPOLL
and the read_lock() fails, so I could go ahead testing it:

This is disgusting, let's just disallow console output from such
locations.  Defer them to a workqueue if their output is so critical.

I did that patch just to see the backtrace in the serial console
and to keep testing it. It's not a solution at all.

Just to be clear, the second problem isn't related to that patch
and the console message is already in a workqueue.
