Apparantly not.  If I'm reading this right, it thinks it's at #24 at
boot, and can't find it.  (Ref. attached 2.2.19-failed).

No.  (Ref. attached 2.2.19-reset-attempt.)

Also, I attached a script log of the rmmod/insmod, and the the resulting
vortex-diag output afterward (Ref. attached 2.2.19-rmmod-insmod).

I'll buy that.  However, I've crawled through the system, and there's nothing
that could be preempting that interrupt as far as I can tell.  And it begs
the question of why does the interrupt work under 2.2.19?
