+/* Seeing somewhat random behaviour on my Nehalem system with auto-save of guest MSRs;
+ * for some strange reason the CPU doesn't save the MSRs during the VM-exit.
+ * Clearly visible with a dual VCPU configured OpenSolaris 200906 live cd VM.
+/* The MSR auto load/store does not work for KERNEL_GS_BASE MSR, thus we
+ * handle this MSR manually. See @bugref{6208}. This is clearly visible while
+ * booting Solaris 11 (11.1 b19) VMs with 2 Cpus.
+ *
  * Note: change the assembly files when enabling this! (remove the manual auto load/save)
+ * Note: don't forget to update the assembly files while modifying this!
