how did you get it to recognise this controller?  kernel command line?
stock RH7's kernel 2.2.16-22 doesn't have automatic support.  I'd be
interested to know if 2.2.17-14 does, as I could use this on a system.

This is normal for a blank disk; hopefully that's all this is.

this is fine. just a note for the inexperienced.

normal - related to first message.

although it doesn't look like it's necessary, it's a good idea to
reboot here. (it usually gives a additional error if reboot needed)

sounds like an overflow.  try using badblocks to verify that the kernel
will allow access to all sectors in the partition.

badblocks -b 1024 -sv `fdisk -s /dev/hde1`

if that works, it looks like overflow in mke2fs or e2fs libraries; try:

delete partition 1 and make 2 more, each half of the disk,

try mke2fs /dev/hde1

if that works try mke2fs /dev/hde2;

if they both work then the overflow is likely the size of the disk;
but you have access to all of it in just two halves, until a fix is found.

Unrelated to disk "problem", you might want to set your PCI latency timer in
BIOS to 64 or more.
