VM bug in pmap code.
Just got core dump. Code is from git, just before compatibility removal.
Oops, I gave swildner bad info. It isn't fixed in c503.
Make sure that machdep.pmap_mmu_optimize is turned off (it should be off by default). We've gotten sporatic reports of this particular panic and have not yet tracked down the reason for it. Nobody can reproduce it reliably which makes tracking the problem down difficult. So if you can find a reproduction case for it, we definitely want to know!
(Also tell as per swildner's first comment whether you are doing this on master or release).

No more cores so far. I think I found a possible trigger for it but that's a sad story. I'm an Enlightement user and I'm still using it (despite it had been removed from dports). When everything starts failing last time I traced that down to /usr/local/lib/ecore/system/upower/v-1.18/module.so. When that file was present Terminology was crashing on start almost each time (except when started before E17, still crashing but not that fast). And a core was happening when I was switching to another window. Since E17 is modular the only thing I had to do is to remove the file and everything was magically fixed!
