Hello, using a 3.14 kernel in a Linux VM running on HyperV (Windows Server 2008 R2) we get following error:
hv_netvsc: hv_netvsc channel opened successfully hv_netvsc vmbus_0_9 (unregistered net_device): Unable to complete receive buffer initialization with NetVsp - status 2 hv_netvsc vmbus_0_9 (unregistered net_device): unable to connect to NetVSP - -22 hv_netvsc vmbus_0_9 (unregistered net_device): unable to add netvsc device (ret -22) hv_netvsc: probe of vmbus_0_9 failed with error -22 Bisecting the problem shows that commit b679ef73edc251f6d200a7dd2396e9fef9e36fc3 is responsible. Reverting it fixes the issue. Even only changing NETVSC_RECEIVE_BUFFER_SIZE to 2M fixes the issue! The virtual machine has 2 GiB of memory and 4 CPUs. Can I provide more information to track down the problem?
