Hi list!
[1.] One line summary of the problem: Network hang: "eth0: Tx timed out (f0080), is buffer full?"
[2.] Full description of the problem/report:
We had to reboot a server twice after a network card hang.
The first time was after one day uptime.
The second time, yesterday, after 8 days uptime.
The server is a dual AMD Athlon(tm) MP 2200+ with 1 GB RAM and is running SuSE Linux 9.2.
There are 2 NIC's on this system, a 10/100 Mbit/s 3Com Corporation 3c905C-TX/TX-M [Tornado] which is not being used and a D-Link System Inc DL2000-based Gigabit Ethernet card.
The problem seems to be the dl2k driver for this second NIC.
The last minutes previous to the network hang and system hard reset (local login is not possible because of nfs mounts hang) the following lines were logged in /var/log/messages:
Dec 8 10:36:55 urutu kernel: eth0: HostError! IntStatus 0002.
Dec 8 10:36:55 urutu kernel: klogd 1.4.1, ---------- state change ----------
Dec 8 10:38:48 urutu kernel: nfs: server jupiter not responding, still trying
Dec 8 10:39:48 urutu kernel: nfs: server diablo not responding, still trying
Dec 8 10:40:21 urutu kernel: eth0: Tx timed out (f0080), is buffer full? Dec 8 10:43:25 urutu kernel: NETDEV WATCHDOG: eth0: transmit timed out Dec 8 10:43:25 urutu kernel: eth0: Tx timed out (d0080), is buffer full? Dec 8 10:46:57 urutu kernel: NETDEV WATCHDOG: eth0: transmit timed out Dec 8 10:46:57 urutu kernel: eth0: Tx timed out (b0080), is buffer full?
On another thread I read that doing a ifconfg eth? down and up again would be enough to regain connectivity again.
Also just ping flooding the card will hang it.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=281819
The hardware wasn't changed the last months. The problem appeared after updating the 4th December from SuSE 9.0 (kernel 2.4.xx) to SuSE 9.2 (kernel 2.6.8).
The card is configured as eth1 but the error above shows eth0! The 3Com card was detected as eth0 and it's down.
The dl2k driver was last updated 2002/10/03. I didn't find any maintainer listed in the Maintainers file.
Any idea what's happening? Should I go back to 2.4.xx? This is a production server with different people logged in using VNC, so testing changes is not so easy.
Many thanks, Richard
