[FreeBSD 7-STABLE/i386] Hello, I've got a 100 % reproductible panic with ipsec when using a 'ping -s 4000'. It works without ipsec My ipsec setup is very simple, i just use setkey: /etc/ipsec.conf flush; spdflush; add 192.168.1.21 192.168.1.200 esp 1011 -E rijndael-cbc "0123456789012345"; add 192.168.1.200 192.168.1.21 esp 1012 -E rijndael-cbc

Two machines (NFS Server: running ZFS / Client: disk-less), both are running FreeBSD r253506. The NFS client starts to deadlock processes within a few hours. It usually gets worse from there on. The processes stay in "D" state. I haven't been able to reproduce it when I want it to happen. I only have to wait a few hours until the deadlocks occur when traffic to the client machine

As others have noted, Tor's patch appears to be a total solution to the recent instability the PAE patch introduced. So, if you're experiencing panics with a recent kernel, or are in a position to stress a machine, please cvsup and give it a test!
