I investigated a little bit deeper, but am stil clueless: _changed 20:20 CET: no more clueless._ A couple of days ago I removed the PCMCIA CAN-Card which was innocently sitting in my cardslot for months. Maybe it received a different configuration when I re-inserted it. After removal of the CAN-Card, the system reboots as usual. Thank you for your assistance. > 1.

I also think it is a network problem because if I boot into a runlevel w/o network, the system does not freeze. It also does not freeze when I remove the network card from the configuration. My /etc/hosts is 127.0.0.1 localhost ::1 localhost ipv6-localhost ipv6-loopback fe00::0 ipv6-localnet ff00::0 ipv6-mcastprefix ff02::1 ipv6-allnodes ff02::2 ipv6-allrouters ff02::3 ipv6-allhosts 127.0.0.2 esw44.mdom1 esw44 and was set up automatically by yast-setuptool When the freeze occurs, the cursor stops blinking, the animated ball on the boot screen stops jumping and the system won't react to anything (ctrl-c, ctrl-alt-del etc), only power-off and display brightness. A cold boot always works, and it also boots up correctly when I do a warm reboot (shutdown -r now) but switch off the power the moment the bios screen appears. >> 1.

In the "bad init" sequence, the file ends after /etc/init.d/rc5.d/S05network start In the "good init" sequence, I cut the rest of the file after the configuration of eth0. ppp0 is started next (manual dialup w/ cellphone). After that, hotplugging services are started. >> 2. When you say the system "hangs" and "freezes", how carefully have you >> assessed that? How long have you waited before giving up?

I will let the machine sit overnight trying to boot, but I dont think it will bring us further. Is there a possibility to redirect >> 3. What is eth0 and how does it connect to the Internet?
