My setup:
Slackware 13.37
kernel 2.6.37.6-smp
ethercat-1.5.1 (configured with --enable-e1000)
I get a kernel Oops when I invoke /etc/init.d/ethercat start.
Sometimes the machine hangs completely other times I can get more details
from syslog:

Apr 3 11:57:07 c130ctltst2 python: hp-systray[2215]: error: hp-systray
