Message:

trpmGCExitTrap: Check for VMCPU_FF_SELM_SYNC_GDT, VMCPU_FF_SELM_SYNC_LDT and VMCPU_FF_SELM_SYNC_TSS if rc is VINF_SUCCESS and return with VINF_SELM_SYNC_GDT to ring-3. Seen when cr4.VME is changed and a trap is forwarded shortly afterwards. The FF remains set and causes TRPM to assert in the forwarding code (debug only).
