This particular problem is one I haven't seen. But I've had problems with USB harddisks freezing when trying to write large files. It seems that not USB<->ATA chipsets are created equal, and the 7.x USB stack seems to have problems with that. > It seems most likely that this is a USB level problem involving the USB > drivers. I am using FreeBSD 7.1. It is annoying behaviour to say the > least and I wonder what can be done about it, Try 8.0-PRERELEASE. The USB stack has been rewritten for 8.x, and my limited testing so far indicates it to work better with quirky hardware. The problem of a panic when unplugging a mounted USB drive should also be fixed. And even if you still have problems with the 8.x USB stack, I suspect the USB stack in 8.x is more likely to receive TLC than the one in 7.x, so it would be best to check that out.
