Hi all,
I have strange problem:
NIC:
alc0@pci0:2:0:0: class=0x020000 card=0x38a317aa chip=0x10621969
rev=0xc0 hdr=0x00 vendor = 'Attansic (Now owned by Atheros)'
device = 'Atheros AR8132 PCI-E Fast Ethernet Controller
(AR8132)' class = network
subclass = ethernet
% uname -a
FreeBSD laptop.minsk.domain 9.0-CURRENT FreeBSD 9.0-CURRENT #8 r209973:
Tue Jul 13 10:17:08 EEST 2010
root@laptop.minsk.domain:/usr/obj/usr/src/sys/b450 i386
I'm using if_alc as a kernel module, when I boot with plugged in
cable all works fine, but when I booting with unplugged
cable - network doesn't work.
I'm trying kenv hw.alc.msi_disable=1 and kldload if_alc..

how to repeat:
1) boot with unplugged cable (if_alc_load="YES" on loader.conf)
2) plug-in cable
3) dhclient alc0
4) tcpdump -ni alc0 -vvv -> http://tiger.ipfw.ru/files/tcpdump.txt
5) reboot with plugged cable..
6) dhclient alc0
....
[tiger@laptop]~%ifconfig alc0
alc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu
1500
options=c3198<VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MCAST,WOL_MAGIC,VLAN_HWTSO,LINKSTATE>

192.168.9.255 media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
now I can unplug cable, unload if_alc, load it again, plug cable -- all
works fine..
Thanks in advance....
