I have installed a fresh FreeBSD 8.0/amd64 to an external USB drive.
I have an UFS2 filesystem on there with softupdates enabled.
But now when there is heavy IO for example while extracting a port the system pauses for a few seconds every once and while and then continues on without any problem. No error pops up anywhere. I have no problems while doing normal IO. There are no other devices connected to the usb bus.
Anybody got any idea what might be going on?
