FC9 : Pb with sata_via adaptor and sata disk

[Jean-Philippe Battu]

Hello

On my linux box, I use a pci adaptor to provide sata port because my 
motherboard doesn't
have serial ata port. My sata adaptor is a :

# lspci
...
02:0b.0 RAID bus controller: VIA Technologies, Inc. VT6421 IDE RAID 
Controller (rev 50)
...
#

When the system boots, the sata disk is well recognized. I can use fdisk 
and mkfs to build
a filesystem without any problems

But, when I try to mount this filesystems, I can see these errors in the 
/var/log/messages
kernel: EXT3-fs error (device sdc2): ext3_check_descriptors: Inode table 
for group 4 not in group (block 99331)!
kernel: EXT3-fs: group descriptors corrupted!

If I use mkfs.ext3 command instead mkfs, I can't see this message but only :
kernel: VFS: Can't find ext3 filesystem on dev sdc1

fdisk -l /dev/sdc   gives me:

Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x198a1989

   Device Boot      Start         End      Blocks   Id  System

/dev/sdc2           60790      121601   488472390   83  Linux

this disk has been worked well on another machine. Is there any problem with
the sata_via kernel modules:
[root at mercure ~]# lsmod | grep sata
