First off, I have successfully hotplugged my USB mouse on this machine, so I don't think my configuration is wrong.

My config:

kernel 2.4.0-pre9
modutils 2.4.0 + David Brownell's depmod patch. The latest hotplug package from the linux-hotplug site. usbutils is not installed.

I just tested and got this:

Jan 22 02:20:35 agate kernel: cs: socket c4ffa000 timed out during 
reset.  Try increasing setup_delay.
Jan 22 02:20:36 agate kernel: cs: cb_alloc(bus 5): vendor 0x1045, device 
0xc861

0x000c0010 0x00ffffff 0x00000000

It looks to me like something is hosed in creating this entry. We don't want the vendor/device IDs to be "0xffffffff 0xffffffff", do we? How are those values getting into the modules.pcimap file?

Also interesting is the fact that during the boot process, my 3c575 cardbus ethernet PC Card was noticed, but no hotplug events happened for it:

device 01:00.0.

Instead, when I loaded the driver by hand, the hotplug event got triggered:

Jan 22 02:22:23 agate kernel: eth0: using default media MII

Here is the modules.pcimap line that shows that there should have been a match:

0x00000000 0x00000000 0x0000001a

Lastly, I am getting a SCSI hotplug error early in the boot cycle.

    Jan 22 02:12:47 agate kernel: request_module[scsi_hostadapter]: Root

fs not mounted

I thought this was fixed?

This is where things start to come unstuck. The NIC isn't reset properly and its PCI space subsequently seems to read as mostly 0xff's.

I'd roll out my standard answer: "turn off ACPI", but I don't think you're using ACPI?

Something's screwy in the cardbus initialisation and I don't know what. I assume everything works OK if you eject and reseat the card?

Mostly.

Perhaps you could stick a `show_trace(0)' into request_module() where this print happens, feed the dmesg output through ksymoops?

In reply to Miles Lane

BTW: What action is this hotplug call supposed to accomplish?

Jan 22 10:40:45 agate /sbin/hotplug: arguments (net) env

(ACTION=register TERM=dumb HOSTTYPE=i386 PATH=/bin:/sbin:/usr/sbin:/usr/bin HOME=/ SHELL=/bin/bash DEBUG=yes INTERFACE=eth0 OSTYPE=Linux SHLVL=1 _=/usr/bin/env)

When I load the 3c59x driver by hand (the hotplug "add" hotplug event isn't loading the driver), this "register" hotplug process kicks off. However, it doesn't do anything I can determine, like run "ifup eth0".

You need to apply that patch to /etc/hotplug/pci.agent that was sent by at the beginning of last week (from Dan Zink @ COmpaq). The PCI ID syntax changed again, it uses colons not "/" ... one hopes it stays stable now!

Likely you just need that patch.

And, I see no sign of "ifup eth0" being run.

What would syslog show though? I know that MII messages come out of pegasus when the interface is brought up.

You should check whether "ifconfig eth0" shows that it's up.

So, has CVS been updated with these changes? Also, isn't a new release set needed in the download section of
http://sourceforge.net/project/showfiles.php?group_id679 ?

I'll give that a try, thanks!
