Re: ml310 kernel2.6 booting problems

I'm also having some problem with my systemace file system. I'm working with
secretlab git, and I try to mount the CF card with xsysace and with xsa, but
in both cases it can't mount the rootfs:

Linux/PPC load: console=ttyS0,9600 root=/dev/xsa3 rw  
:
:
:
[    2.777706] xsysace xsysace.0: Xilinx SystemACE revision 1.0.12

[    2.913383]  xsa: unknown partition table

:
[    3.398810] Please append a correct "root=" boot option; here are the
availa:

[    3.547926] Kernel panic - not syncing: VFS: Unable to mount root fs on
unkn)

Does this mean that I have configured incorrectly the file system options in
the kernel??
I have read that the solution to this is to change the DOS/FAT/NT Filesystem
option to the below configuration:

      <*> Second extended fs support 
DOS/FAT/NT Filesystems
       < > MSDOS fs support                                            
       < > VFAT (Windows-95) fs support                                
       < > NTFS file system support 
  [*] Advanced partition selection                                
         [*]   PC BIOS (MSDOS partition tables) support 
I've already tested this configuration:

      <*> Second extended fs support 
DOS/FAT/NT Filesystems
       <*> MSDOS fs support                                            
       <*> VFAT (Windows-95) fs support                                
       < > NTFS file system support 
  [] Advanced partition selection                                
     

My CF card has the following structure:

Disco /dev/sdc: 521 MB, 521773056 bytes
16 cabezas, 63 sectores/pistas, 1011 cilindros
Unidades = cilindros de 1008 * 512 = 516096 bytes
Disk identifier: 0x00000000

Disposit. Inicio    Comienzo      Fin      Bloques  Id  Sistema
/dev/sdc1               1         400      201568+   6  FAT16
/dev/sdc2             401         500       50400   82  Linux swap / Solaris
/dev/sdc3             501        1011      257544   83  Linux

I'm also wondering if I should use xsysace or xsa, because I have search in
the file xsysace.c for the name of the device and It is named as xsysace. Am
I right, and should I use xsysace? Or this name isn't related with the /dev
file??
$ grep xsysace xsysace.c

        .name = "xsysace",
        ace_major = register_blkdev(ace_major, "xsysace");
                printk(KERN_WARNING "xsysace: register_blkdev() failed\n");
        unregister_blkdev(ace_major, "xsysace");

I'm going to reformat my CF card and test it,maybe the partition table is
corrupted, but fdisk is not saying anything at all.

Thanks
