Thanks for the pointers. I have FC4 on another box with the USB2
connected to it. I am getting about 35 MB/s reads (VIA chipset), and
about 15-20 MB/s writes. The context switching is horrible, and drives
the processor load way up.
I will install the new Centosplus RPMs for the kernel. I presume I
can do it via yum and adding it into the repos. Thanks.
