Thanks for the reminder. Apologies that this slipped through :( > As a solution > 1. flush after reset when we know there will be no more interrupts > 2. add a flag to disable config access before reset It's crude, but it works. Applied. If this happens again, do we want a "__virtio_device_disable" which stops any interrupts from being delivered? That would make this neater, though the implementation might be a bit nasty. Thanks, Rusty. _______________________________________________ Virtualization mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/virtualization
