well, nice to hear its working, but wierd about the messages. > dmesg here: http://krogh.cc/~jesper/dmesg-ko-2.6.27.20.txt > > [476197.380486] e1000: eth3: e1000_clean_tx_irq: Detected Tx Unit Hang > [476197.380488] Tx Queue <0> > [476197.380489] TDH <c> > [476197.380490] TDT <63> > [476197.380490] next_to_use <63> > [476197.380491] next_to_clean <b> > [476197.380491] buffer_info[next_to_clean] > [476197.380492] time_stamp <10717579a> > [476197.380492] next_to_watch <f> > [476197.380493] jiffies <107175a3e> > [476197.380494] next_to_watch.status <0> > > The system has been up for 14 days but the dmesg-buffer has allready > overflown with these. I looked at your dmesg and it appears that there is never a NETDEV_WATCHDOG message, which would normally indicate that the driver isn't resetting itself out of the problem. Does ethtool -S eth3 show any tx_timeout_count ? > Configuratoin is a 4 x 1GbitE bond all with Intel NICs > > 06:01.0 Ethernet controller: Intel Corporation 82546EB Gigabit Ethernet > Controller (Copper) (rev 03) > 06:01.1 Ethernet controller: Intel Corporation 82546EB Gigabit Ethernet > Controller (Copper) (rev 03) > 06:02.0 Ethernet controller: Intel Corporation 82546EB Gigabit Ethernet > Controller (Copper) (rev 03) > 06:02.1 Ethernet controller: Intel Corporation 82546EB Gigabit Ethernet > Controller (Copper) (rev 03) are you doing testing with the remote end of this link? I'm wondering if something changed in the kernel that is causing remote link down events to not stop the tx queue (our hardware just completely stops in its tracks w.r.t tx when link goes down) ------------------------------------------------------------------------------ This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
