rtai - kernel panic

Hello all,
I wanted to install a RTAI kernel for my Opensuse 10.2 with kernel 2.6.16. I am using the linux-kernel 2.6.20 and rtai version 3.5
I managed to set up all the configurations required and ran the following

make clean bzImage modules
make modules_install

and after that the mkinitrd. I have the reiserfs file-system and I compiled it as modules as I was getting the dependency error when I compiled it included. Also the ATA_PIIX i compiled as module.

All this went all right. And after that I configured the /boot/grub. And after restarting i get the kernel panic error

not syncing: VFS: Unable to mount root fs on unknown-block(0,0)".

I checked the configuration using the ls -ld /dev/sda1 command and it shows
brw-r----- 1 root disk 8, 5 2009-6-2 /dev/sda1

I believe here 8 and 5 are for the block and partition. I dont how to set this for the new kernel. I think it trying to access (0,0) is wrong. But maybe I am doing a mistake somewhere else. I am not sure if its better to use ext3 than reiserfs.

Any help and suggestions would be very useful. Thanks.

I had the same problem but with ext3, it looks like the ext2 file system is needed in the boot process, so include it in the kernel.

I changed the filesystem to ext3 and it somehow seemed to work. I was even able to run the rtai latency tests. But after installing my network driver and starting it the system just hangs up. I dont have a clue what could be the problem here
