My system: intel ICH9R, 4 hard disks, two raid arrays (raid0 and raid5).

Ubuntu 8.04 installed on raid0 array works well with dmraid
1.0.0.rc14-0ubuntu3.1, capable of read/write raid0 and raid5.

Ubuntu 8.10 intrepid could not boot because dmraid print this error 8 times:
ERROR: isw device for volume "zerovol" broken on /dev/sda in RAID set 
"isw_baeaijeeda_zerovol"
ERROR: isw: wrong # of devices in RAID set "isw_baeaijeeda_zerovol" [8/4] on 
/dev/sda

I have followed instructions in another bug to change libata hpa option
and updated initramfs, but dmraid has the same error message.


Now I have updated dmraid version to 1.0.0.rc14-2ubuntu13 (Phillip Susi), and 
the "wrong # of devices" error has disappeared, when I chroot to Ubuntu 8.10 
from Ubuntu 8.04 everything in dmraid seems ok, but during boot the system 
cannot access to root partition in the raid5 array and a initram console 
appears.

Thanks in advance.
