Hi,
I've been getting a very reproducable panic in -CURRENT with moderate
network traffic (including same-machine traffic, and especially
with ssh), and a LOR on boot.
kiwi# uname -a
FreeBSD kiwi.petecurry.net 7.0-CURRENT FreeBSD 7.0-CURRENT #1: Sun
Sep 9 11:01:03 CDT 2007 root@:/usr/obj/usr/src/sys/KIWIKERN amd64
The source is from about 10:00 this morning, and my kernel config
and dmesg output is attached. It's been happening for at least a
few weeks, about as long as I've been running -CURRENT and had this
machine.
The LOR message is:
Sep 9 11:16:00 kiwi kernel: lock order reversal: (sleepable after non-sleepable)
