Well, the bug happens when bringing up the interface. # modprobe rt_igb [ 117.274639] rt_igb 0000:03:00.0: Intel(R) Gigabit Ethernet Network Connection [ 117.281800] rt_igb 0000:03:00.0: enp3s0: (PCIe:2.5Gb/s:Width x1) 22:20:47:8d:0f:c9 [ 117.289397] rt_igb 0000:03:00.0: enp3s0: PBA No: FFFFFF-0FF [ 117.294997] rt_igb 0000:03:00.0: Using MSI-X interrupts. 1 rx queue(s), 1 tx queue(s) [ 117.303500] [Xenomai] HIPASE PPS on SDP0 [ 117.307529] sdhci-pci 0000:00:1b.0: SDHCI controller found [8086:5aca] (rev b) # rtifconfig enp3s0 up [ 166.503855] spurious APIC interrupt through vector ff on CPU#0, should never happen. > Are those interrupts MSI or MSI-X?
