This problem hits me as well:
```load: 1.48  cmd: ifconfig 1272 [runnable] 18.73r 0.00u 0.00s 0% 3020k
mi_switch+0xc1 sched_bind+0x74 epoch_drain_callbacks+0x15c
if_detach_internal+0x60 if_vmove+0x3c ifhwioctl+0x1013 ifioctl+0x50c
kern_ioctl+0x26d sys_ioctl+0xf6 amd64_syscall+0x10c fast_syscall_common+0xf8

Any luck on the fix?
