Hi

Kernel boot problem:
Obviousely the kernel was too large. When reduce its size and put some
extensions into modules, it starts up fine.

But there are 2 other problems:

Ethernet Card:

- When I insert a Xircom Ethernet card, it is detected and the modules are loaded.
But somehow it affects the NFS connection in such a bad way, that it looses connection
to the server. Everything gets very slow. When I plug the pc card out, NFS works fine again.

I guess that too many interrupts knock the system out.

ATA Flash card:

- Even worse with the flash card: The system crashes!

- Is the request_irq related to the loaded module or to the IDE stuff in the kernel?
  ('Configure IDE for ATA on PCMCIA' is switched off!)
- Is it right that every occurence of request_irq has to replaced with request_8xxirq?
