2.6.10 kernel and block device /dev/hdd2 problem

After compiling kernel 2.6.10 I am getting this error during boot up:

block device /dev/hdd2 is not a valid root device

Here is my grub setup (by the way the 2.6.9 kernel workes fine and it's real_root=/dev/hdd2 setting is correct)

default=0

timeout=15

splashimage=(hd1,0)/grub/splash.xpm.gz

Can you please post the partitions you have on both hard drives?

What filesystem is / on? (ext3, reiserfs, etx2 )
You probably didn't compile support for it in the kernel, or its compiled as a module and not preloaded in your ramdisk.

Hi!

I'm a bit confused here. How come it can find both your kernels if they are both in /boot but the kernel-lines in your grub.conf are different? (one pointing to /boot/ and the other one to /)

Maybe I'm missing something!?

I moved my hdd to ide1 as a slave which would now make it hdb2. I think that might have been the problem. I will post my results once I get some results. By the way the type is ext2 and ext3 for my partitions and yes I did include support for it during the compile.

"I moved my hdd to ide1 as a slave which would now make it hdb2"

Not necessarily, if you also have only one other hard drive it will be hdb , but if you also have a cdrom then it will be hdc . . . 2 reffering to the partition . . . try "df" if you think your numbers / letters might be awry.

I remember I got into a right guddle when I couldnt remember which drive was on which cable.

Mind Grub only counts the HARD-DRIVES ! and from zero up . . . . same with its partitions, from zero up then jumping to 5 for the first logical eg hd1 1 being the 2nd partition on the second hard drive.
