Title: Failure when creating multiple VMs with sr-iov port Status in linux package in Ubuntu: New Bug description: When creating a multiple in the row KVM instances with an SR-IOV interface this way: manually - openstack port create --vnic-type direct --network sriov-net sriov-portN (2 sec pause) - openstack server create --port sriov-portN --image bionic-sriov --availability-zone nova:hostname --flavor m1.small --key-name maaskey test-sriovN (2 sec pause) and x 5 times. The host hangs, stops being accessible via juju ssh, ssh attempt to bondm address gets connection refused. Icmp to host gets response though. If I type password manually in ilo console - there is no bash prompt after it. After rebooting I found the following in journalctl : Oct 29 08:26:23 hostname kernel: general protection fault: 0000 [#1] SMP PTI Oct 29 08:26:23 hostname kernel: CPU: 8 PID: 7405 Comm: libvirtd Not tainted 5.0.0-32-generic #34~18.04.2-Ubuntu Oct 29 08:26:23 hostname kernel: Hardware name: HPE ProLiant DL380 Gen10/ProLiant DL380 Gen10, BIOS U30 05/21/2019 Oct 29 08:26:23 hostname kernel: RIP: 0010:i40e_sync_vsi_filters+0xaa/0xca0 [i40e] Oct 29 08:26:23 hostname kernel: Code: 00 00 00 48 89 85 78 ff ff ff 48 8b 83 10 02 00 00 48 c1 e8 03 48 89 85 70 ff ff ff 83 e0 01 88 45 8b 48 8b 03 48 85 c0 74 17 <8b> 80 38 02 00 00 8b b3 0c 02 00 00 31 c6 89 83 0c 02 00 00 89 75 Oct 29 08:26:23 hostname kernel: RSP: 0018:ffffb91a77ac7708 EFLAGS: 00010286 Oct 29 08:26:23 hostname kernel: RAX: 8287194a20ac1de7 RBX: ffff9c5594638000 RCX: 0000000000000000 Oct 29 08:26:23 hostname kernel: RDX: 0000000000000001 RSI: 00000000fffffe01 RDI: ffff9c5594638000 Oct 29 08:26:23 hostname kernel: RBP: ffffb91a77ac77b0 R08: 0000000000000000 R09: 00000000000024f8 Oct 29 08:26:23 hostname kernel: R10: 00000000000024f8 R11: 0000000000003e25 R12: ffff9c57670e2580 Oct 29 08:26:23 hostname kernel: R13: ffff9c5594638000 R14: ffff9c5763896000 R15: ffff9c5594638a28 Oct 29 08:26:23 hostname kernel: FS: 00007f386be92700(0000) GS:ffff9c077f800000(0000) knlGS:0000000000000000 Oct 29 08:26:23 hostname kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Oct 29 08:26:23 hostname kernel: CR2: 00007f3851d53e17 CR3: 0000004d76f4e003 CR4: 00000000007626e0 Oct 29 08:26:23 hostname kernel: DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 Oct 29 08:26:23 hostname kernel: DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Oct 29 08:26:23 hostname kernel: PKRU: 55555554 Oct 29 08:26:23 hostname kernel: Call Trace: Oct 29 08:26:23 hostname kernel: ?
