I can trigger it by just extracting the ports tree onto the raid. It usually stops several times for over a minute doing nothing before continuing. While building KDE it stopped for good when extracting a port. The bsdtar process was hanging there in the wdrain status. Waited over 60 minutes before interrupting the process. I haven't seen any messages in dmesg. I'll try to build with debug support tonight and see if it makes a difference. The version was the one delivered with the PC-BSD 8.1RC discs but also after upgrading to the newest RELENG_8 sources the problem persists. The hardware is fairly new and other OSes show no problems so i'm inclined to say that the hardware isn't faulty ;) I could also try to install a 8.0 system if it helps to determine if a regression in 8.1 is the problem.
