[tlug] Kernel 2.6.5 Compiling problem

[Alessandro Mantelli【HOBIBOX】 <alex@example.com>]

Hello, I have installed Debian Sarge and partitioned as following:

/boot     ext3
swap
/           xfs

In the menuconfig I select to add in the kernel and not to compile as module
both ext3 and xfs file system.
Neverteless I have the following error on restart:

Cannot open root device hdb7 or unknoww block (0,0)
Please append a a correct "root=" boot option.

Note
1) In the kernel 2.4 original present in sarge there are the same boot
options and it works
2) I compiled the kernel patching it with the Nvidia driver
3) I complied the kernel in the debian way: make-kpkg kernel-image
modules-image
4) I apt-geted install module-init-tools

Is there something missing? Do you know why kernel can't find the partition
even if all the needed
modules are compiled in? Maybe a compatibility problem with the Nvidia
drivers?
Any Clue?

Thanks

Alex
