I've found that writing USB mounted async easily hangs or traps the kernel but I can write whole /boot/modules (over 30MB, lots of files) without a problem if USB is moused "noasync". That is, no soft-updates, no async and not "sync" - plain old good default mounting mode. It is slow but much more stable.
