SubjectATM ENI Problems with SMP
Date
Hi there,

I have an Efficient ENI 155 ATM adapter running with Linux 2.4.16/17.
When I turn on SMP support (The board is an ASUS P2B-DS with two P3/800), the
eni driver crashes with "driver error - ident mismatch"-Error.

Without SMP support activated in the kernel, the card works fine.


Is there a problem with SMP-Support for ATM?


I turned on the ENI_DEBUG-option, the output is:
