Description of problem: Booting a 32bit rawhide client on a RHEL5.1 64bit host causes a kernel panic. Version-Release number of selected component (if applicable): 2.6.25-0.18.rc8.fc9.i686.xen How reproducible: Always Steps to Reproduce: 1. get a 32bit RawHide image 2. run it on a RHEL 5.1 64bit host Actual results: Kernel panic - not syncing: Attempted to kill the idle task! Expected results: Client boots Additional info: Host is RHEL 5.1, fully up to date. Client is rawhide, fully up to date. This was working earlier in the year but I haven't started it for a while. When I did start it I ran yum update and rebooted. Since then I have had this error. I can still boot on the old kernel: 2.6.21.7-2892.fc9.i686.xen

Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
There are a couple of things going on here: it's possible that this was either a bug in the F-9 i386 xen kernel, or a bug in the RHEL 5.1 32-bit PV on 64-bit host support. In any case, I've now been able to successfully boot a 32-bit F-9 guest on both a 5.2 and 5.3 64-bit Xen system. Can you try this again and see if it now works? Thanks, Chris Lalancette
Hi, this works for me now, thanks :)
Thanks
