Promise PDC20267 / ide bug?

I've just reinstalled a box with 6.1-RELEASE on a
Promise PDC20267 RAID 0+1 ARRAY.
On boot the BIOS says the array is "functional"
but FreeBSD claims its running in DEGRADED mode.

[dmesg]
ad4: 190782MB <WDC WD2000JB-00GVA0 08.02D08> at ata2-master UDMA100
ad5: 114473MB <WDC WD1200JB-00DUA3 75.13B75> at ata2-slave UDMA100
ad6: 114473MB <WDC WD1200JB-00GVA0 08.02D08> at ata3-master UDMA100
ad7: 114473MB <WDC WD1200JB-00GVA0 08.02D08> at ata3-slave UDMA100
ar0: WARNING - mirror protection lost. RAID0+1 array in DEGRADED mode
ar0: 228946MB <Promise Fasttrak RAID0+1 (stripe 64 KB)> status: DEGRADED
ar0: disk0 DOWN no device found for this subdisk
ar0: disk1 READY (master) using ad5 at ata2-slave
ar0: disk2 READY (mirror) using ad6 at ata3-master
ar0: disk3 READY (mirror) using ad7 at ata3-slave
[/dmesg]

atacontrol status ar0
ar0: ATA RAID0+1 stripesize=128 subdisks: DOWN ad5 ad6 ad7 status: DEGRADED

I believe the problem is due to the size of ad4 which
is a 200Gb disk as I had no spare 120's to replace
the failed disk for this install. I think this is
causing BSD to error as the RAID bios only listed it
as a ~120GB i.e. only slightly bigger than other
120's.

Has anyone see this before? Is it a bug with the ide
driver?
