[ ... ]

The KSEs (their appear to be at least 3 of them)
are waiting for work.  The lone kse_wakeup() is
trying to wake one up, but it doesn't appear to
be woken at least in this snippet.  The parameter
to kse_release() and kse_wakeup() is the address
of the KSE's mailbox (each KSE has one mailbox).

I don't know what the (null)'s are.  What does
ktrace show?
