Bug 105877

Where does the RH9 version die? (matchNetDevices is new...)

Here is a backtrace from kudzu-0.99.99 extracted from the src.rpm of redhat 9.

Can you attach the output of lspci?

I add my network-scripts files and module.conf

The 'current CVS' segfault should be fixed in current CVS (it's also
bug 106332).

I did cvs up, compiled, but it still segfaults. However it doesn't
seems to segfault at the same place. It now segfaults where kudzu-0.99 
did. I guess the other bug hide this one...

Fixed in CVS, now, really. At least, that particular one is.

Yep, fixed now. No more segfault. Thanks ! I think you can close it.

Will be fixed in 1.1.43-1.
