@york-king There were several changes related to the performance optimization and the maximum transfer size between build 187 and 189. Can you please post the qemu command line and IoMeter...

@york-king Thanks a lot. Let me ask QE to reproduce the issue. Best, Vadim.

@cosmedd Would it be possible to share the crash dump file? Thanks, Vadim.

@smasharov Since it is FreeBSD, can you try limiting the maximum transfer length by adding ",max_sectors=32" to virtio-scsi-pci device's parameters: In your case it should be something like this: -device...

@gang929 Can you please post the qemu command line? Thanks, Vadim,

maybe information in https://github.com/virtio-win/kvm-guest-drivers-windows/issues/805 can be helpful for you.

Thanks, Can not promise anything, but I will try my best to check this issue by end of the next week. Don't hesitate to ping me if you see no...
