[Bug 192353] Re: 100% CPU usage during disk I/O with SATA/PATA

[TheFluffyOne]

Have taken advise from the LKML and the IOWait figures are considered
normal -- they indicate the time the CPU spends idle waiting for IO.
Other processes can make use of these idle cycles, so although the CPU
appears pegged at 100% it does in fact still have available cycles.
