hotplug problem [was: hotplug vs pcmcia-cs]
Hi, everyone,
First of all, sorry for starting my previous thread by replying to
another mail (by mistake). Secondly, sorry for replying it without
properly displaying sender's name (due to an un-configed mutt. usually,
I send mail through mozilla-mail like now).
Anyway, I think it's better to start a fresh thread. History is
copied as following.

I will definitely read them.

Unfortunately, I think it's a 16-bit PC-Card, because I need to enable
some ISA support (can't remember the exact name) in kernel to use it.
Anyway, it's Linksys WPC11 card "Instant Wireless Network PC Card".

Quoted from http://qref.sourceforge.net/Debian/reference/ch-gateway.en.html
For 16 bit ISA PCMCIA network cards:
hotplug / ifupdown with locally disabled /etc/pcmcia/network
(recommended), or
pcmcia-cs / ifupdown with default /etc/pcmcia/network (deprecated), or
pcmcia-cs customized by enabling features of /etc/pcmcia/network
(deprecated)
I would love to have first approach working. And I think I am quite
close now. If I completely disable pcmcia-cs (including cardmgr), when I
insert card, nothing happends. "ifup eth1" says "No such device". If I
run "cardmgr" while disable pcmcia-cs's network config script, after
inserting card, hotplug is able to get notified, and bring up eth1
successfully using /etc/network/interfaces. BTW, all related driver
modules are loaded all the time, and cardmgr won't load any new modules.
So apparently, without cardmgr, the kernel seems fail to bind the driver
(orinoco_cs) to eth1, and then notify hotplug. And cardmgr does something
to bind them. Once eth1 is binded, hotplug can happily manage them. I
tried adding "alias eth1 orinoco_cs" in /etc/modules.conf, doesn't help.
Anything I am missing?

testing (sarge).
And thank you for the reply!
