Hello Florian,

thanks for your responds and sorry for my late answer. Now to
your objections:

Ok, the next one will come within the mail and I tried to keep any line
below 80 culomns.

Right, the activation part is not Jensen-Alpha specific but is a kind of
a goodie for 2.4.x kernels to force the configuration of an lne390
adapter despite of different settings with the EISA configuration
utility. On the SRM console of the Jensen Alpha this is even obligatory
since that console does not initialize any EISA cards but the Adaptec
1740 for system start.

I think in kernel 2.6 you would do it more cleanly with the /sys
filesystem.
A problem is also, that the patch above should apply well on the lne390.c
source of the 2.6 kernel but since I run kernel 2.4.27 I have no way to
actually test that code.

Is it possible to merge fixes for 2.4.36 first?

With kind regards,
