https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236042 Bug ID: 236042 Summary: Windows Server 2016 Hyper-V snapshot triggers SCSI errors Product: Base System Version: 12.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: alex.gacovski@gmail.com Hi, Currently running FreeBSD 12.0-RELEASE in a Hyper-V Gen 2 with a SCSI virtual disk. When Veeam backup takes a hyperv snapshot of the running vm this is printed on the console.

The system has 1 virtual disk with 3 partitions. * EFI boot * swap * UFS root file system Thank you. Cheers, Alex. -- You are receiving this mail because: You are the assignee for the bug.help
