Problems with Promise IDE controller under 2.4.1

We experience trouble with the Promise (PDC20265) IDE controller
and seven 75GB IBM disks on a single CPU (Pentium-III) server.

Linux 2.4.1 fails to detect correct geometry for the four last
disks (identified as hde, hdf, hdg, hdh).

Two types of disks:
(geometry of the first is correctly detected, the second isn't)


[root@nngds1 /root]# hdparm /dev/hda


/dev/hda:
 multcount    =  0 (off)
 I/O support  =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 nowerr       =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 9345/255/63, sectors = 150136560, start = 0


[root@nngds1 /root]# hdparm /dev/hde


/dev/hde:
 multcount    =  0 (off)
 I/O support  =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 nowerr       =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 17873/16/63, sectors = 150136560, start = 0




The machine runs RedHat 7.0 with RHN upgrades if it means anything.
