It is caused by the fact, that the driver of the card does not create
the expected "device" symlink in the class device's sysfs representation,
pointing to the physical device in sysfs. This symlink is necessary for
e.g. modern hardware integration to match the virtual with the physical
device.
1.
PCMCIA-sysfs is not supported now, but already in the -mm kernel, so this
should be fixed sooner than later.
2.
The latest wait_for_sysfs in the udev package will not print any error for
net devices.
3.
Kernel 2.6.10* and later will add what we can expect in sysfs to the hotplug
event, so we can handle that right, without useless waiting for the symlink
and printing errors.
o.k.? :)
