Just one more piece of information: a simple recompile isn't what has
fixed the problem every time, the recompile has involved an upgrade
to 2.6.16 as well

I seem to be having a problem with CentOS releases 4.2 and 4.3. On
a fresh install (on two very different pieces of hardware, one Dell
PowerEdge server and one Compaq Presario), the system seems to be
extremely slow. It happens primarily during any hard disk I/O.
It's slow enough that my mouse skips slowly instead of moving
smoothly, and I am unable to type. It seems to freeze for
milliseconds at a time, which makes typing difficult because while
it is frozen it seems to not accept keystrokes (that is, if I type
the letter 'f' twelve times, only four of them may appear,
depending on timing). It may be unrelated, but the clock seems to
go more slowly during I/O as well (i.e. during times of I/O the
clock runs behind more and more). If I were to extract a large
tarball, I would have to wait for the while thing to finish before
I could interact with the system at all
A simple recompile of the kernel from kernel.org sources (which, as
you can imagine, takes quite a long time) fixes the problem
entirely, though. So is there something that differs wildly
regarding the I/O scheduler between the stock CentOS kernel and the
stock kernel from kernel.org?
It would really be more convenient to be able to keep our kernel up-
to-date automatically using the built-in packaging tools, so I hope
that someone has seen the problem and has a work-around
