removing external usb hdd without unmounting causes reboot?

[Momchil Ivanov]

Hi,

I am running FreeBSD 6.2-STABLE #11: Sat Jul 14 16:27:12 CEST 2007 and 
accidently unplugged the USB hub to which my external hdd together with a 
mouse were connected and this caused my machine to freeze for some seconds 
and then reboot. At that moment the hdd was mounted and I was playing music 
out of it.
After that I tried to reproduce it :) so just plugged only the hdd directly, 
mounted it and started playing music files from it. When I unplugged the USB 
cable the same thing happened: short freeze, and then reboot.
Is this expected behaviour? And is there some way to avoid the freeze and 
reboot?

Thanks.
