https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235246 --- Comment #5 from pr@aoek.com --- Patch is for head, I only have 12s around, so I applied the patch (no too cleanly, required some manual edit) but it did not work: em0: <Intel(R) PRO/1000 Network Connection> port 0xec00-0xec1f mem 0xfe9e0000-0xfe9fffff,0xfe9dc000-0xfe9dffff irq 17 at device 0.0 on pci11 em0: Using 1024 tx descriptors and 1024 rx descriptors em0: Using 0 rx queues 0 tx queues em0: Using MSI-X interrupts with 1 vectors em0: failed to allocate IRQ for rid 0, name irq0. em0: iflib_legacy_setup failed 12 device_attach: em0 attach returned 12 Disabling MSI-X in loader.conf (with a stock kernel) did the trick: em0: <Intel(R) PRO/1000 Network Connection> port 0xec00-0xec1f mem 0xfe9e0000-0xfe9fffff,0xfe9dc000-0xfe9dffff irq 17 at device 0.0 on pci11 em0: attach_pre capping queues at 1 em0: using 1024 tx descriptors and 1024 rx descriptors em0: msix_init qsets capped at 1 em0: System has MSIX disabled=20 em0: Using an MSI interrupt em0: allocated for 1 tx_queues em0: allocated for 1 rx_queues em0: Ethernet address: bc:ae:c5:33:6d:98 em0: netmap queues/slots: TX 1/1024, RX 1/1024 Which is different but similar to how it was under 11.2: em0: <Intel(R) PRO/1000 Network Connection 7.6.1-k> port 0xec00-0xec1f mem 0xfe9e0000-0xfe9fffff,0xfe9dc000-0xfe9dffff irq 17 at device 0.0 on pci11 em0: Using an MSI interrupt em0: Ethernet address: bc:ae:c5:33:6d:98 em0: netmap queues/slots: TX 1/1024, RX 1/1024 Before we close we shall test the patch under head, I cannot at the moment = as the Intels I have are all in production.
