wait_for_sysfs on Fedora Core 3

wait_for_sysfs on Fedora Core 3

[Nik]

Hi all,

I am porting a PCMCIA network driver, which I did not originally write, 
from kernel 2.4 to 2.6. I am at a stage where the driver works on a 
Fedora Core 3 (kernel 2.6.9-1.667) machine, and I can communicate 
through it, but I see the following error message in the system log:

 > wait_for_sysfs[5466]: either wait_for_sysfs (udev 039) needs an update
 > to handle the device '/class/net/ibut0' properly (no device symlink)
 > or the sysfs-support of your device's driver needs to be fixed, please
 > report to <linux-hotplug-devel@lists.sourceforge.net>

The driver registers a new ethernet device (interface) using its own 
family of names. The default family is "ibut", and so the first in that 
family is "ibut0".

The two calls I have used to register this interface in the 2.6 port are:

alloc_etherdev(...) and register_netdev(...)

I have been unable to determine if I should fix this message by updating 
some config files to recognise the "ibut" interfaces; or by changing 
something in the driver; or whether I should change/update something in 
sysfs/udev on the machine.

When searching he logs I also found the following similar entry:

 > wait_for_sysfs[12532]: either wait_for_sysfs (udev 039) needs an
 > update to handle the device '/class/net/tun0' properly (no device
 > symlink) or the sysfs-support of your device's driver needs to be

I presume this is caused by my recent installation of OpenVPN which uses 
the TUN interface. Again, I am able to communicate successfully through 
the TUN adaptor.

Could someone please point me in the direction(s) in which I should 
proceed to fix these?

All suggestions or comments gratefully received.

Cheers!
Nik.

You are running an obsolete version of udev. Please upgrade it.

No problem. Would anyone be able to tell me the oldest and and newest 
version that I should install on Fedora Core 3? yum could only find 
version 039-10, which I'm guessing still too old. The newest RPMs I 
could find were 050, but they were for Fedora devel. On kernel.org I 
have found 057. Is this too new for Fedora Core 3 (kernel 2.6.9)?

Thank you again for your help already.

Cheers!
Nik.
