What's going on is a bug in the kernel. If you can reboot your machine, logon from the console, and examine the system log, you might be able to find a "kernel oops" that can be decoded and submitted to the kernel developers for their review. Oh, and while you're logged on, you might want to clear out your iptables list until you're ready to recreate the problem, or test the fix.

Hello, I have activated module iptables as a dynamic firewall (blocking incoming connections, but allowing communication started by user). When I tried telnet to this client on a blocked port I got the following message on VM console: Welcome to SuSE SLES-7 (s390) - Kernel 2.4.7-SuSE-SMP (console). linuxvm login: ip_tables: (c)2000 Netfilter core team ip_conntrack (1024 buckets, 8192 max) Kernel panic: misaligned (__u32 *) in __xchg In interrupt handler - not syncing HCPGIR450W CP entered; disabled wait PSW 000A0000 801B41D0 What is going on?
