I am not able to reproduce the same behaviour on 2.6.30.9, had it been on all versions - this can safely be termed as behaviour. But from 2.6.31 onwards this is very much reproducable, especially the change in behaviour of writing to disk.
I will try more things and update if I can find anything new in this.
Thanks,

corruption regardless of the filesystem you are using. Even if you
are lucky enough that there was is no IO being issued while the
device is unplugged, what guarantee is there that the device even
comes back with the same device name? Further, if the device is usb
powered, there is no guarantee that the drive caches were
flushed correctly before the unplug so random log and metadata
corruptions are definitely possible.
