I'm trying to compile the latest kernel, but I'm getting the following errors. Any idea what the problem is?

i doesn't know what's the matter but i think you can just desactivate the ps2esdi in your kernel config and so no matters of compile

Yep, did that. The Compile seemed to go ok, but when I try to install the resulting debian kernel image I get the following errors:

And when I try booting the new kernel, I get the following message:

Kernel panic: VFS: Unable to mount root fs on unknown-block(0,0)

Is loopback compiled into the kernel or as a module, one of the two?

Google hits

module.

Nevermind, I think my thought is a red herring. Let me read your errors again.....

Well, I recompiled the kernel with loopback device support compiled into the kernel, but I still get exactly the same ide errors when installing the compiled kernel.

And I still get the Kernel panic error when trying to boot to the new kernel.

Post your kernel config for the pci, ide and scsi areas. I think there might be a problem somewhere in that area.

Ok, managed to fix all the ide errors, and the kernel installed fine.

However when I try to boot to the new kernel, I'm now getting a different kernel panic error:

Kernel panic: VFS: Unable to mount root fs on hda7

Anyway, here's my ide and scsi config:
