RHEL 5.0 through 5.7 in i686 and x86_64 variants. All are configured identically. Additionally there are 2 VMs with 6GB of memory running RHEL 5.4 and 5.5 i686, but otherwise configured identically. The only VMs that trigger this internal error are the RHEL 5.6 and RHEL 5.7 i686 guests. So far there seems to be no formula to reproduce, the VMs can be completely idle or they can be in the middle of a GCC compile for the issue to trigger. The problem did not occur on the same hardware running 2.6.38. If you can think of any further information necessary, please let me know and I'll get it. -- Doug Goldstein -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
