Re: IO slowdown with latest FC4 kernel

Dave,
thanks for the quick response.. Looks like the testing is gonna need to 
be a little more extensive. After some time using the old kernel, the 
initial performance dropped to the same levels that 1526 was showing 
right after boot.

It's onboard IDE controller. DMA enabled on both disks (two seagate 
disks, using udma 5 , with 80 way cable).
The controller is recognized by lspci as
00:11.1 IDE interface: VIA Technologies, Inc. 
VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 06)

I'll do some massive testing tomorrow to try to exclude the possibility 
of HW failure, since the fact that both kernels show the same results 
(even though 1526 shows it faster than 1456) makes me believe he may 
need to get either a new disk or a new motherboard.
