I have two nearly identical machines at two locations.
Or maybe not quite identical.. very nearly anyway.
Machine running somewhat modified RedHat Rawhide
2.4.21-20.1.2024.2.1.nptlmea receives RAs from a cisco
router, and autoconfigures nicely.
Machine running RedHat Rawhide Fedora 2.4.22-1.2115.nptlsmp
kernel fails to autoconf. That machine is receives RAs from
a NetBSD router's rtadvd.
Both machines run without any specific things to particularly
enable IPv6 in their configurations. Besides of auto-loading
the ipv6 module.
Oddly the functioning pair isn't configured with EUI64=y setting,
but the failing one is. Yet the cisco is configured to send
EUI64 RAs...
Any ideas ?
