FC18 Intel RAID not working

$

Hello friends,

After having problems with FC17 upgrade, I switched to FC18.

In FC17 I had a working Intel software RAID-1 with 2 drives. This required to remove the rd.dm=0 at kernel boot configuration (an earlier post). FC17 was smart to remember that choice, automatically configure the RAID array to be available as partition under /dev/md126p1 and it worked perfectly (until some issues came up after upgrading FC17 recently).
As for FC18, at initial boot into setup (live media), I also removed that definition to enable RAID support. But after installation, grub config includes rd.md=0, so I had to manually remove it.
In addition, even after removal and reboot, RAID is not properly configured and accessible to the system.
I don't want to go through a procedure that requires some assembly/create or others with mdadm, since it's awkward.
The question is how can this be resolved, if at all?
dmesg output:
Code:

[    2.444554] md: bind<sdb>
[    2.647110] md: bind<sdc>
[    2.650695] md: bind<sdb>
[    2.650912] md: bind<sdc>
.....
[    4.398623] md: export_rdev(sdb)
[    4.398645] md: export_rdev(sdc)

As for RAID, it's a simple software raid by Intel, well supported under FC17.
The system is pretty new and up-to-date (Core i7 Ivy-Bridge + H77 chipset).

It seem like the raid is not properly configured in the system.
Running:
Code:

# ll /dev/md*
/dev/md126
/dev/md127
/dev/md/imsm -> ../md127

# mdadm -D /dev/md126
/dev/md126:
Container : /dev/md/imsm0, member 0
Raid Level : -unknown-
Raid Devices : 2
Total Devices : 2

State : active, Not Started
Active Devices : 2
Working Devices : 2
Failed Devices : 0
Spare Devices : 0

Number Major Minor RaidDevice State
1 8 32 0 active sync /dev/sdc
0 8 16 1 active sync /dev/sdb

Is it possible the necessary module wasn't built into the kernel?

Any ideas are more than welcome.

Thanks,
Moti.

Another command to manually assemble the array prints:
Code:
