Actual Results:

HPT372: IDE controller on PCI bus 00 dev 98
HPT372: chipset revision 5
HPT372: not 100% native mode: will probe irqs later
HPT37X: using 33MHz PCI clock
    ide2: BM-DMA at 0xc400-0xc407, BIOS settings: hde:DMA, hdf:pio
    ide3: BM-DMA at 0xc408-0xc40f, BIOS settings: hdg:DMA, hdh:pio
hde: MAXTOR 6L040J2, ATA DISK drive
hdg: MAXTOR 6L040J2, ATA DISK drive
ide2 at 0xb400-0xb407,0xb802 on irq 10
ide3 at 0xbc00-0xbc07,0xc002 on irq 10
hde: 78177792 sectors (40027 MB) w/1819KiB Cache, CHS=77557/16/63, UDMA(100)

Hardware Involved:

Athlon XP 1800+ (not overclocked)
1024M of Mushkin Level 2 PC2100 DDR SDRAM (2 x 512)
ABIT KR7A-RAID (older one with VT8233 south bridge)
ATI Rage 128 Pro (16M)
Intel Pro/100 S Server Adapter
2 x 40G Maxtor D740X ATA/133 7200 RPM drives each connected as the master to 
the two ATA/133 interfaces provided by onboard HPT372 (using driver provided 
in RH7.3 kernel by default), using _SOFTWARE_ RAID to mirror hde to hdg
