Error loading custom kernel

[psilocybin]

I am dual booting 10.6 and 10.5. 10.5 loads fine
getting an error - unable to load custom kernel when trying to boot my 10.6 from the same bootloader. It's Cham rc3. Any help?

It sounds like it's trying to load the 10.5.x kernel when it's booting Snow Leopard?

"is it plugged in" type question: Are you using Vanilla kernel and is it named mach_kernel..?

Does it boot if you select the Snow partition and type mach_kernel arch=i386 -v at the boot prompt?

Or does it do the same thing?
