Re: Disk very slow with VIA KT400 in 2.4.18 (stock RedHat 8.0)

[Tupshin Harper <tupshin@tupshin.com>]

Other people know substantially more about this than I do, but there 
were a number of fixes for KT400 problems, especially IDE in recent 
kernels. I would give 4.2.21-pre3 or 4.2.21-pre3-ac4 a try. I've used 
both of those with relatively few problems on a KT400 machine.
