This is presumably what's hooked up in g_eli_create():
/*
* Spoiling cannot happen actually, because we keep provider open for
* writing all the time or provider is read-only.
*/
gp->spoiled = g_eli_orphan_spoil_assert;
The backtrace makes me think that coming out of resume will cause a
media change event on the cd0 device, which sounds a _little_ odd, but
may be necessary due to Stupid Reality Crap. That pushes a spoil
event down to g_eli. And g_eli seems to assume that can't happen to
a thing it's got around an open.
With the caveat that I'm no expert on ELI or GEOM, and any advice I
might give could just be the trigger for a nasal demon invasion of our
world, one thing you might try is taking that event as a hint to just
blow away the .eli device; treat it like an orphan. So changing that
callback to using the g_eli_orphan func instead. e.g., something like
