I have a Compaq Presario 12XL325 laptop which continues to have problems
with some kernel hacking options (see bugzilla 973). While I continue to
test new bitkeeper and -mm kernel builds, I also work around them by
building a kernel with the problematic options disabled in order to test
other features.
While testing the new kernel builds I have run across a problem loading
the pcmcia network drivers (SMC 2632W wireless ethernet card). My pcmcia
controller is defined as follows:

The operating environment is RedHat 9. I have enclosed various system
files I figure to be of interest.
Attachment 1 is the configuration used to build the kernel
Attachment 2 is /proc/interrupts
Attachment 3 is /proc/ioports
Attachment 4 is the full lspci output for my system
However, the following show the
difference between how 2.4 handles card insertion events vs. how 2.6-test
handles those events. Maybe someone could either tell me this is a kernel
problem, or else say how I could update my system to handle this situation
in 2.6. Thanks in advance.
First, here is how 2.4 handles the events:

network hotplug changed slightly in 2.6 so the kernel passes: 'add' instead of 'register'
to the scripts. This is because network devices are kobjects and go through the generic
hotplug path.
The fix is:

This fix is in the last released version of the hotplug package if
people just want to use that instead of patching their scripts (it also
has some other 2.6 fixes in it.)
