Just got another crash. I started rsync to copy a dozen of small files
but it was taking ages. Ssh connection was quite fast, I was able to
check dmesg output, but the system hung when I ran dmesg again.
Dmesg output was full of these messages:

urtwn0: could not send firmware command 5
urtwn0: could not send firmware command 5
urtwn0: discarding oversize frame (len=1516)
urtwn0: could not send firmware command 5
