I griped about the vn device a month or two ago, with a small amount of primary swap and a large vn swap device I could freeze the system at will when I started swapping to the vn device. *However*, I also found and fixed a hardware problem (summertime, ambient temp increased 10F, caused a cpu to overheat) that probably was the real cause. Anyway, tossing the vn device fixed the problem then, but by chasing the (reproducible) symptoms of the real problem to a completely different spot. (As an aside, then the system was completely stable except for building the world, it would hang every time at the exact same spot in the build, hardware is so much fun :). Haven't seen any vn problems since (but haven't looked either). The origin of the vn complaints was a comment by Dyson about vn "instability" when he was in the midst of VM mods in March or thereabouts. I'm a very happy camper now, looking forward to the elf stuff coming in. Russell To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
