I posted previously that since reinstalling RH [6.1]
that my system is not as responsive as it was before
the reinstall.  The only differences between then and
now is that I added an 8.4GB hdd as hda, reduced
the number of partitions to 3 (excluding swap, of
course), and added 64 megs more ram for a total of
256MB.  The partitions are / on /dev/hda5, /home on
/dev/hdc5, and /tmp on /dev/hdb5.  The problem is
that during ocassional drive activity, my mouse pointer
becomes jerky.  During an operation like compiling,
it becomes so jerky that it is difficult to do
anything else.

I have a ps/2 trackball that works very well (logitech).
I have checked irqs and io ports and there are no
magically created conflicts.  I have a celeron 366 and
all the latest 6.1 updates installed.  I also have
my own compiled version of kernel 2.2.13.

I thought there might be something about my partitioning
that is leading to this poor performance.  RH is
installed on /dev/hdb5, which is about 4 GB in size.
The first partition is a primary partition that I created
for a reinstall of Windoze (dev/hda1).  It is empty as
of now and not yet formatted.

I took a look at my message log last night before
giving up for the evening and saw this repetitive
entry multiple times, and now assume that it is
related to the problem:

Dec 12 00:33:06 Tempus kernel: hda: status timeout: status=0xd0
{ Busy }
Dec 12 00:33:06 Tempus kernel: hdb: DMA disabled
Dec 12 00:33:06 Tempus kernel: hda: no DRQ after issuing WRITE
Dec 12 00:33:07 Tempus kernel: ide0: reset: success
Dec 12 00:47:17 Tempus kernel: hda: status timeout: status=0xd0
{ Busy }
Dec 12 00:47:17 Tempus kernel: hda: no DRQ after issuing WRITE
Dec 12 00:47:17 Tempus kernel: ide0: reset: success

Except for the 'hdb:  DMA disabled' entry, the others
are repeated again and again.  On hdb is the mountpoint for
/tmp.  I am assuming, at this point, that part of the problem
revolves around the DMA disabled message, and that the rest
may also play a part.  How do I correct whatever the problem
is here?

The drives are properly identified by both bios and linux
during bootup.  The new drive is Seagate atapi/ide 8.4GB
drive.
