Back in April, 2007, I opened this bug because of problems with "NETDEV WATCHDOG: eth0: transmit timed out" errors.
I found that changing one of my BIOS settings seemed to make the problem go away. The setup menu named "Resource Configuration" offers a setting named "Shared PCI IRQs". I found that if I left this set to the original "Auto", then I would have the problems described in the bug report, making the network unusable; but if I changed this setting to "Share Three IRQs", then everything seemed to work OK. I ran like this for several months without seeing the problem. Sometime around October/November, in the midst of several kernel revisions, the problem returned briefly, but before I had time to investigate it, yet another kernel upgrade or two seemed to get me back to normal. (All these are the standard etch kernels 2.6.18-686, as pushed to me by security updates). This morning I finally got around to installing a big batch of recent security updates, including a new kernel, and I'm sorry to report that I'm seeing NETDEV WATCHDOG network paralysis again. Previous to rebooting this morning, the machine was up for 19 days, without problems -- previous boot was December 18th, Linux version 2.6.18-5-686 (Debian 2.6.18.dfsg.1-13etch5). Today's version ran OK for approximately 13 hours, then went into continuous network lockup. Today's version is: Linux version 2.6.18-5-686 (Debian 2.6.18.dfsg.1-17). Here is a little kern.log extract showing the end of the reboot, and the start of the lockup: Jan 6 01:16:26 legba kernel: IPv6 over IPv4 tunneling driver Jan 6 01:16:26 legba kernel: 0000:00:10.0: tulip_stop_rxtx() failed Jan 6 01:16:26 legba kernel: eth0: Setting full-duplex based on MII#1 link partner capability of 41e1.

Any suggestions for what I should experiment with, are welcome. Any other information you might want, will be happily provided. On this new reboot, I added the kernel parameter "pci=routeirq" as my own experiment with this, but the box has only been up for about an hour, so I can't say for sure if it helps. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
