I don't see a code path where the original value isn't restored. Can you do a few things for me: The output of: cat /proc/sys/dev/raid/speed_limit_min cat /proc/sys/dev/raid/speed_limit_max If the value is 0 here, skip ahead. If hte value is non-zero, run and send me the output of: sh -x /etc/init.d/hdparm start cat /proc/sys/dev/raid/speed_limit_min cat /proc/sys/dev/raid/speed_limit_max If the value of either of those files is 0 after this, then there is pretty definitely a bug. If they have a non-zero value here, then it might be something else. Finally, if the values are zero, can you run: echo 6000 > /proc/sys/dev/raid/speed_limit_min echo 6000 > /proc/sys/dev/raid/speed_limit_max and send me the output of: cat /proc/sys/dev/raid/speed_limit_min cat /proc/sys/dev/raid/speed_limit_max Hopefully that's clear enough.
