We got this bt after setting kernel dump stuff up. For some reason kgdb did
not find debugging symbols, even though the kernel was compiled with -g.
Hopefully this helps and I will go dig some more to find why we don't have a
debug symbol.
#0 0xc0674fae in doadump ()
#1 0xc067550a in boot ()

Sorry to waste your time. I discovered a similar PR with unp_gc and there
may be a patch already. I will see if that works.
Thanks,
Benjie

Well I spoke too soon. I increased the load even more and it crashed again.
Same IP. So FYI, mpsafenet did not work, although it did allow me to stress
the system for longer than I've ever done before. Perhaps that just reduced
the concurrency enough. I will try kernel trace next.
Thanks,

You are right, they may not be the same. From first look it seems like they
are similar based on the description of the problems -- system stable, then
under load related to network, get panic after different time intervals. I
just assumed that kernel is typically stable enough that this kind of

I will try to get a kernel trace -- it may not happen for awhile since I am
not in the office and working remotely for awhile so it may not be easy to
get a trace... but I will check.
It looks like the problem reported by that link, and some of the links from
there though...

Not in the sense of transmuting a sleep mutex into a spin mutex, no.
sleep mutexes will spin when the lock holder is currently running, but
this happens within the context of the mtx_lock_sleep function itself.
Ok, thanks, this clears
Hi FreeBSD hackers and engineers,
I am experiencing a kernel panic that comes on when my new PowerEdge 1950

on the list who have given me useful comments, some of which I am still
following up. But I wanted to send a

So this could mean that independent stress tests will not result in panic if
there aren't enough concurrency to cause the problem.

Surely it cannot be since it involves a different function ;-)
