I have next configuration:

Gigabyte P35-DS4 Bios F14c
2 x Seagate 320 GB RAID 0 Intel Matrix Storage:
    Dual Boot XP + Windows 7
1 x Seagate 160 GB
    Ubuntu 10.04

When I boot to Ubuntu and reboot, first member Raid fail (it says Non-Raid Disk) and i cannot boot to Windows partitions.
I need to power off computer for the first member appears.

By HDAT2 i have disabled HPA, same problem occurs: first member Raid fail (it says Non-Raid Disk) and i cannot boot to Windows partitions. Obviosly, Intel Matrix Storage need to HPA.
I have reactivated HPA to recover RAID.

hdparm command don't show HPA :

$ sudo hdparm -N /dev/sda
/dev/sda:
 max sectors = 625142448/4385456(625142448?), HPA setting seems invalid (buggy kernel device driver?)

but kern.log shows it:

$ grep -i HPA /var/log/kern.log
Jul 4 12:58:42 gubi kernel: [ 1.373053] ata3.00: HPA unlocked: 625140335 -> 625142448, native 625142448

What to do ?

I prefer to keep the RAID, but i need Ubuntu.
