https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=271275 Bug ID: 271275 Summary: [Hyper-V] Kernel cannot attach 4th NIC Product: Base System Version: Unspecified Hardware: amd64 OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: email@example.com On Hyper-V virtual machines with Windows Server 2008 R2 as host, FreeBSD fails to attach more than three network adapters. During boot the attach of the 4th (and consequently the 5th, 6th, ...) NIC, called as hn3, returns the error message: hn3: <Hyper-V Network Interface> on vmbus0 hn3: gpadl_conn(chan13) failed: 3221225540 hn3: chim gpadl conn failed: 5 device_attach: hn3 attach returned 5 I've run several tests and the problem occurs on all versions of FreeBSD (I've tried from 10.4 onwards). It shouldn't be a Hyper-V bug because on other guest OSes, like Windows or Debian, the problem doesn't occur. -- You are receiving this mail because: You are the assignee for the bug.
