Description Pete Zaitcev 2004-06-30 02:43:00 EDT
modprobe ipv6 says that per_cpu____icmpv6_socket undefined,
which is a static variable in net/ipv6/icmp.c.
This happens because all references to that variable are
done by asm code in percpu.h and gcc optimized the variable away.

Comment 6 Dave Jones 2005-04-16 01:02:00 EDT
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.
