I am experiencing this issue in Intrepid.
I have an external hard drive (WD) that is hooked up by a USB cable. Small files transfer fine, and the HD works flawlessly in vista. However, using Ubuntu, During large file transfers, the system randomly locks up.
At the start of the transfer the transfer looks smooth (i.e. the ##mB transfered increments steadily), then it starts jumping up instead of steadily increasing (i.e. it jumps from 90mB to 120 then to 150, etc..) and then it stops at a certain point. Usually this point is over 500MB, but other than that it seems to be random (even when transfering the same file, it stops at different points). When I try to close the transfer or cancel it, the window does not respond. Then after a few seconds the desktop background and the top/bottom ubuntu panels become frozen. I can restart GDM, but doesn't solve the problem - GDM doesn't load properly - only loads background I think. I try to shutdown, and it wouldn't do it... GDM closes but then it gives me some text (something about SDC), and sits there, so I have to do a forced reboot. The message that it gives me wasn't very helpful anyway, it made little sense. If someone wants to diagnose the issue properly, please let me know and I'll try it again and tell you the message. Also, ubuntu won't start up again unless I shut off the external hard drive and turn it on again.

A few times I was able to close the transfer (can't remember how, but I remember it involved waiting for like 5 minutes). Then I did "lsusb" and the hard drive doesn't show up. I tried shutting off the HD, turning it on, and it won't show up, and I couldn't mount it in ANY WAY So I ended up having to reboot the system and the HD before they can work again.
Here are my specs:
Thinkpad Notebook T61, 2.0Ghz, 2GB 667Mhz DDR ram, X3100 video card, usb 2.0, 80GB SATA internal drive
Ubuntu: Intrepid Ibex (did fresh Intrepid install, and applied ONLY critical updates --> still problem)
