This is a known issue which Intel have a repro for and are investigating. It appears to be hardware issue with an interaction between the Local APIC and mwait. http://xenbits.xen.org/gitweb/?p=xen.git;a=commitdiff;h=7b653a245ffc26aca691f34204d4fef7af49a0a0 which is in staging but not in rc4 should work around it in the common case. ~Andrew _______________________________________________ Xen-devel mailing list [email protected] https://lists.xenproject.org/mailman/listinfo/xen-devel
