Hi.
I get "Device busy" when trying to change VLAN-id on a sub-if to em0:
[root@host /home/user]# ifconfig vlan100 vlan 100 vlandev em0
ifconfig: SIOCSETVLAN: Device busy
[root@host /home/user]# dmesg | grep em0
em0: <Intel(R) PRO/1000 Network Connection Version - 6.2.9> port
0x4000-0x401f mem 0xee200000-0xee21ffff irq 16 at device 0.0 on pci9
[root@host /home/user]# pciconf -vl
em0@pci9:0:0: class=0x020000 card=0x108c15d9 chip=0x108c8086 rev=0x03
hdr=0x00
vendor = 'Intel Corporation'
device = 'PRO/1000 PM'
class = network
subclass = ethernet
[root@host /home/user]# uname -a
FreeBSD host 6.2-STABLE FreeBSD 6.2-STABLE #1: Tue Sep 25 22:29:05 CEST
2007 user@host:/usr/obj/usr/src/sys/host i386
It works if I create a new interface like:
[root@host /home/user]# ifconfig vlan100 create
and setting the vid and vlandev:
[root@host /home/user]# ifconfig vlan100 vlan 100 vlandev em0
But when I try to change the setting:
[root@host /home/user]# ifconfig vlan100 vlan 100 vlandev em1
ifconfig: SIOCSETVLAN: Device busy
Even if I destroy the interface and create it again I get "Device busy":
[root@host /home/user]# ifconfig vlan100 destroy
[root@host /home/user]# ifconfig vlan100 create
[root@host /home/user]# ifconfig vlan100 vlan 100 vlandev em1
ifconfig: SIOCSETVLAN: Device busy
Motherboard is Supermicro PDSMi-LN4+ with four em-interfaces.
How do I solve this?
