You mentioned this happens in all filesystems so it's not an EXT4 problem.
You also said it's a USB drive, which leads me to think it might be the
following issue with the ehci_hcd kernel module, which I also have:

You can verify this by tailing /var/log/kern.log and looking for USB related
errors when pv's traffic stalls.
The current lame fixup is to rmmod ehci_hcd, thus switching to USB 1.1 and
limiting transfer rate to 1.5MB/s. I also suggest you try to md5 without
ehci_hcd to see if the problem stops happening.
