Actually, while we wait for an answer and if you feel like doing a
bit more experimenting, it would also be interesting to see if the
failure after a long while is truly the same as the failure after
a very short while.

So if you could reproduce it again, but

- then either not restart WLAN before taking the dmesg, or

- just hope WLAN will stay up long enough for you to take dmesg before
  another error pushes the first one out of the message buffer, or

- before starting the test, set  log_buf_len=2M  in  bootargs_base  in
  the u-boot environment, and then retrieve the kernel messages with
  dmesg -s 2000000

... that would be great.
