I'm not totally certain of why this is (I don't know enough about the
hardware involved), but I'm told that with this patch some drives will
lose their geometry translation after a reset/unwedge. After that, the
driver will be using one set of cylinder/head/sector geometries and the
disk will be using another, leading to file system data corruption.
If it works for you, then you're lucky/fine. It does cause problems for
Charles Hannum has mentioned in conversation that he'd like to see a
