[OpenIndiana-discuss] "bad mutex" crash?

[Richard Lowe]

If you save the dump (savecore), extract it (savecore -vf vmdump.0 -d
.), and run mdb (mdb unix.0 vmcore.0)
What does:

   fffffffff7f9a9c5::whatis

say?  The stack looks reasonable enough that I'm wondering if you have
a module loaded someone's stripped that's actually at fault, rather
than it being our fault and a damage stack.  If it says it's a 3rd
party module, I'd suggest reporting a bug to wherever it came from.
Otherwise, please file an illumos bug and make the crash dump
available (over http ideally)?
