When mounting two partitions from a USB dirve, it can cause the drive = access lock up for a long time. Details: Terminal 1 -- term1# mount /dev/da0s3d /mnt term1# cd /mnt ; rm -fr * when rm starts, go to terminal 2 and do: term2# mount /dev/da0s3e /dist ### this will hanging for a long time and = USB hard drive activity light is off. After more than 1-2 minutes, mount returns, and the drive activity light = is blinking, thus removing is going on. term2# ls /dist ### this will cause dUSB dirve hanging again -- no = avtivity. Similarly, ls will finish in a couple of miniutes or longer, the rm = command continues; but for a while, the drive activity will stop again. Reboot machine, repeat the above steps, and result will be the same. = Reboot machine again, and just mount one partition, then doing "rm -rf *" without involve the second partition, = rm will finish quickly. Has anyone obseved this behave on 8.0-RC? -Jin
