(Cross-posting to -net, but I'm not subscribed there... yet) I was wondering if anyone else has experienced this panic when dhclient = tries to get an IP address after booting a recent 12.0-CURRENT kernel? = Using the 12.0-CURRENT AMI from early November works, but with the = latest snapshot or when using a kernel built from source I get this: ixv0: <Intel(R) PRO/10GbE Virtual Function Network Driver> mem = 0xf3000000-0xf3003fff,0xf3004000-0xf3007fff at device 3.0 on pci0 ixv0: using 2048 tx descriptors and 2048 rx descriptors ixv0: msix_init qsets capped at 1 ixv0: pxm cpus: 2 queue msgs: 2 admincnt: 1 ixv0: using 1 rx queues 1 tx queues=20 ixv0: Using MSIX interrupts with 2 vectors ixv0: allocated for 1 queues ixv0: allocated for 1 rx queues taskqgroup_attach_cpu: setaffinity failed: 22 taskqgroup_attach_cpu: setaffinity failed: 22 ixv0: Ethernet address: 0a:ad:68:70:ea:78 ixv0: netmap queues/slots: TX 1/2048, RX 1/2048 ... panic: Assertion if_getdrvflags(ifp) =3D=3D i failed at = /usr/src/sys/net/iflib.c:2199 cpuid =3D 3 time =3D 1515673176 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame = 0xfffffe008a8ee600 vpanic() at vpanic+0x19c/frame 0xfffffe008a8ee680 kassert_panic() at kassert_panic+0x126/frame 0xfffffe008a8ee6f0 iflib_init_locked() at iflib_init_locked+0x75f/frame 0xfffffe008a8ee750 iflib_if_ioctl() at iflib_if_ioctl+0x744/frame 0xfffffe008a8ee7b0 ifioctl() at ifioctl+0x1903/frame 0xfffffe008a8ee850 kern_ioctl() at kern_ioctl+0x2c4/frame 0xfffffe008a8ee8b0 sys_ioctl() at sys_ioctl+0x15c/frame 0xfffffe008a8ee980 amd64_syscall() at amd64_syscall+0x79b/frame 0xfffffe008a8eeab0 Xfast_syscall() at Xfast_syscall+0xfb/frame 0xfffffe008a8eeab0 --- syscall (54, FreeBSD ELF64, sys_ioctl), rip =3D 0x80100a4fa, rsp =3D = 0x7fffffffe408, rbp =3D 0x7fffffffe460 --- Thanks in advance :) -- Bradley T.
