For debuging some Oops+panic I have been needing Mingo's neconsole patch which I found on http://people.redhat.com/mingo/netconsole-patches/. The patch seems quite old, it is for 2.4.10, and it did require a litle work to get applied on latest kernels. Is there a more recent version in another location I don't know about?
I got it working with 2.4.20, but unfortunately my sis900 was not supported. However it was trivial to update sis900 to work with netconsole, I simply made exactly the same modifications as the original patch did to the tulip and the eepro100 driver. The result is here: http://www.daimi.au.dk/~kasperd/linux_kernel/netconsole-2.4.20.patch
Now I have a few questions: 1) When it is so trivial to add support for another ethernet interface, how come there are so few supported? Is there some potential problem, I don't know about? In my case it certainly worked well enough for me to actually get the message on another computer, and that was from an Oops happening inside an IRQ which is if I understood it correctly one of the most tricky contexts. 2) Why does netconsole require the interface to have an IP address? Wouldn't it be possible to specify the source IP address as argument for the module? I´d like to do that to load the netconsole module early. 3) Would it be realistic to implement netconsole support for ethernet cards connected through USB? I have a SB4100 cable modem using the CDCEther driver. 4) Would it be possible to implement a SysRq key to repeat the mesages from the kernel buffer? This could be nice if the message got lost due to network congestion or because the receiving computer was turned off at the moment the crash happened.
