Not sure there's a problem report, but I've seen similar problems with
SDIO bwfm(4) on NanoPi NEO Plus2.  In that case bwfm0 quits working, but
the machine is otherwise responsive on Ethernet and serial console after
that.

Not sure I've seen the "header larger than mbuf" message before though.
I've seen plenty of the "checksum error" ones though.
