https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D271275 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: buccilorenzo@virgilio.it On Hyper-V virtual machines with Windows Server 2008 R2 as host, FreeBSD fa= ils 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. --=20 You are receiving this mail because: You are the assignee for the bug.=
