isn't it fun ?? .. job security ..

- you're running into "ordering" problems ..
	- which modules are run against the hardware  in which order

	- prev sda is now sda in the new kernel if at all etc,
 
- insmod the modules for the missing scsi and ide controllers
	- if the modules doesnt exist or doesnt load, you have no
	choice but to use a newer kernel

- all these probelms diappears when you build your own kernel
  and you may or may not have to remapp  sda to sdb and vice versa
