From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.6) Gecko/20060728 Firefox/1.5.0.6 Description of problem: The current rpms of kernel 2.6.17-1.2174_FC5xen0 and xen-3.0.2-3.FC5 seem to have a problem. If I use shorewall to create a set of iptables rules and xend is running, I get a kernel panic whenever network IO occurs, usually within seconds. If I shut xend down, no panic. The shorewall/iptables rules are relatively minimal. As an experiment, I installed the fc6 kernel -- 2.6.17-1.2517.fc6xen as well as the somewhat later fc6 kernel and the problem was solved. However, due to the mismatch between the kernel and xen (and the fact this is an fc5 system), no guests will start. They crash right when init should be starting. So, somewhere between the 2174 and 2517 kernel versions, this bug was fixed but is not available as an fc5 rpm set. Hence, there doesn't seem to be a working fc5/xen/iptables combo available. Or maybe there is something else wrong on the system. Given the 2517 kernel solved the problem, this seems unlikely. Version-Release number of selected component (if applicable): kernel-xen0-2.6.17-1.2174_FC5 How reproducible: Always Steps to Reproduce: 1. Boot 2.6.17-1.2174_FC5xen0 kernel 2. start xend 3. start shorewall 4. attempt network connector (ssh, samba) Actual Results: Kernel panic and then a reboot Expected Results: no crash Additional info: Here's the output from dmesg: Linux version 2.6.17-1.2174_FC5xen0 (brewbuilder@hs20-bc2-3.build.redhat.com) (gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)) #1 SMP Tue Aug 8 17:03:19 EDT 2006 BIOS-provided physical RAM map: Xen: 0000000000000000 - 000000003b351000 (usable) 115MB HIGHMEM available. 831MB LOWMEM available.
