>Description:
I'm using FreeBSD as a desktop in office.
When I'm closing chrome web browser with lots of tabs, there's a probability that everything will hang (system becomes unresponsive via network, X freezes). Actually I did this like a dozen times for now, and only once I got a LOR (with a freeze for like 2 seconds) instead of a freeze. I think may be this LOR can be the place that's causing the freeze.
here's what I got:
lock order reversal:
1st 0xfffffe004635e4b0 vm object (vm object) @ /usr/src/sys/vm/vm_object.c:511
2nd 0xfffffe0003000180 vm map (system) (vm map (system)) @ /usr/src/sys/vm/vm_map.c:2871
