Danke. I'll make an /events directory and watch for events to get logged and see what's happening.

The Linux kernel does not activate any new devices on s390 by default (its a long discussion why) These devices appear in sysfs (/sys/bus/ccw/devices/.... and /sys/devices/css0/..) trigger a hotplug event and thats it. You can activate these device with scripts, or if hotplug is properly configured, hotplug can activate these devices (IIRC on SUSE the hwup script is called which checks the config files in /etc/sysconfig/hardware/) -- Mit freundlichen Grüßen / Best Regards Christian Borntraeger Linux Software Engineer zSeries Linux & Virtualization ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
