For me looks like something got confused on the HCI packet parsing:
either the kernel, hcidump, or something else. The HCI events after
the LE meta event make no sense (they seem garbage). Did you try with
btmon instead of hcidump ?

Can you save the raw dump using "hcidump -w output.dump"  (or using
btmon -w) and send to the list? It is easier to analyze, as the parser
may be bogus.
