SubjectRE: PCMCIA Cards on 2.4.0

Hi,

My problem was an other problem.

With Kernel 2.4.0test11 and 2.4.0test12, I compile with PCMCIA options
built in the Kernel (not as modules).

Works fine, I start Linux and the PCMCIA that was inserted was recognized
without problems (I think that I could not change PCMCIA because then
don't work, I am not sure)

With Kernel 2.4.0 final, with the same options, I start Linux and don't
work.

Then, with the help of Christian Gennerat, I see (on /var/log/daemon) that
my cardmgr searchs for the module of my card (serial_cs.o, etc.; I haven't
the laptop here). After it, I compile with the PCMCIA suport in kernel
but with the drivers of my cards as module.

Now works fine, I can change the cards without restart :-)

The question is, why with kernel 2.4.0test12 and test11 this options works
fine; and with final release not?

Thank you very much, I hope that my experience help anybody.
