'+' is used in a swi name to indicate that the names of the interrupts to

under the assumption that at least one name would fit. It sounds like in
this case, none fit. We should fix this code, but in the mean time, what
you might consider doing is hacking intr_event_update() in kern_intr.c to
print out overflowing names to the console using printf(9) so you can at
least see what they are. This is the somewhat suspect bit of code:
The code is not suspect as p_comm is of fixed length. Someone just used too
long of a name for a swi handler.
I was wondering whether we might not do better to put as much in as we can but
truncate with a '*', so you at least get a fractional swi name. Under what
situations do we use a single ithread for multiple swi's?
