Current dom0 S3 should work with pci=nomsi. For msi case, we already have workaround which may be sent out soon. The formal solution for msi case which may require config space emulation need more consideration & discussion. Jimmy ^ permalink raw reply [flat|nested] 9+ messages in thread

The hypervisor doesn't automatically restore the vectors to the physical devices, but only does that on a hypercall: physdev_restore_msi. I guess that it works because the S3 during is short and the addr/data are still in the device? > How should i send the machine to sleep? running 's2ram' causes a > segmentation fault...
