 Posted: Sat Nov 15, 2008 7:25 pm Post subject: ethernet card disconnects arbitrarily |
 |
|
got a 09:00.0 Ethernet controller: Broadcom Corporation Device 1698 (rev 10) card on a new laptop, I've left the laptop on during the night.
when I wokeup, I noticed that I didn't had Internet on the laptop, I've restarted the service from command line from there all day long, every 5-10 minutes I need to restart the service.
when I restart the service, dmesg reports this:
| Code: | tg3: eth0: Link is up at 100 Mbps, full duplex.
tg3: eth0: Flow control is off for TX and off for RX.
|
I use sys-apps/ifplugd now when I unplug the cable, knemo still shows that eth0 is connected and receives data!
I've tried to rule out internet problems (my gf's computer had connection when I didn't), iptables, samba dont know what it can be more...
I'm thinking turning ethernet debug in the kernel but I can't seems to find it.
rc-status reports that the service is started when the cable is disconnected when it suppose to show that the connection in inactive

after testing the same conditions on winxp, I deduce that it is a linux issue, anyone has any hints?

more info, dmesg spits out this:
| Code: | NETDEV WATCHDOG: eth0: transmit timed out
tg3: eth0: transmit timed out, resetting
tg3: DEBUG: MAC_TX_STATUS[00000008] MAC_RX_STATUS[00000000]
tg3: DEBUG: RDMAC_STATUS[00000000] WDMAC_STATUS[00000000]
tg3: eth0: Link is down.
device eth0 entered promiscuous mode

probably found the issue, it's catch 22....
adding irqpoll has kernel parameter causes the disconnections, but you need to add irqpoll cause if the dvd which looses irq #17 and causes the computer to freeze...
