Berry,
what's the kernel version of your SLES11 SP1 kernel running? I am aware
of a race problem between udev rules and kernel while accessing a sysfs
attribute of a ccwgroup device. It has been fixed with kernel
2.6.32.49-0.3.1. This problem would match your described symptom
"udevd-event[554]: error opening
ATTR{/sys/devices/qeth/0.0.efac/portname} for writing: No such file or
directory"
