The review mentions setting hw.pci.honor_msi_blacklist="0" and it helps indeed -- worth mentioning in UPDATING? vmx0: <VMware VMXNET3 Ethernet Adapter> port 0x3000-0x300f mem 0xfe903000-0xfe903fff,0xfe902000-0xfe902fff,0xfe900000-0xfe901fff at device 0.0 on pci3 vmx0: Using 512 tx descriptors and 256 rx descriptors vmx0: msix_init qsets capped at 8 vmx0: intr CPUs: 20 queue msgs: 24 admincnt: 1 vmx0: Using 8 rx queues 8 tx queues vmx0: attempting to allocate 9 MSI-X vectors (25 supported) vmx0: failed to allocate 9 MSI-X vectors, err: 6 - using MSI vmx0: attempting to allocate 1 MSI vectors (1 supported) msi: routing MSI IRQ 25 to local APIC 6 vector 48 vmx0: using IRQ 25 for MSI vmx0: Using an MSI interrupt msi: Assigning MSI IRQ 25 to local APIC 25 vector 48 msi: Assigning MSI IRQ 25 to local APIC 24 vector 48 vmx0: bpf attached vmx0: Ethernet address: 00:00:00:00:00:33 vmx0: netmap queues/slots: TX 1/512, RX 1/512 vmx0: device enable command failed! vmx0: link state changed to UP vmx0: device enable command failed!
