(9.2) panic under disk load (gam_server / knlist_remove_kq)
9.2 PRERELEASE (today) / amd64
Hello,
I'm seeing a panic while trying to build a poudriere repository.
As far I can see it always happens when gam_server is started (ie xfce is
running) and under disk load (poudriere bulk build) :
(That is something new, the box was pretty stable)
the complete crash dump (core.0.txt) is here:

NFS deadlock on 9.2-Beta1
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
