Problem Description:
When trying to load the iptables service I get the following error:

Feb  2 16:05:56 alphacrow kernel: ip_tables: (C) 2000-2002 Netfilter core team
Feb  2 16:05:56 alphacrow kernel: Could not allocate 60 bytes percpu data
Feb  2 16:05:56 alphacrow modprobe: WARNING: Error inserting ip_conntrack
(/lib/modules/2.6.9-22.0.2.ECsmp/kernel/net/ipv4/netfilter/ip_conntrack.ko):
Cannot allocate memory
Feb  2 16:05:56 alphacrow kernel: ipt_state: Unknown symbol ip_conntrack_untracked
Feb  2 16:05:56 alphacrow kernel: ipt_state: Unknown symbol need_ip_conntrack
Feb  2 16:05:56 alphacrow modprobe: FATAL: Error inserting ipt_state

Unknown symbol in module, or unknown parameter (see dmesg)
Feb  2 16:05:56 alphacrow iptables:  failed

Occurs on both the 2.6.9 kernel shipped with CentOS 4.2 and also the official
2.6.15.2 kernel I built.

Steps to reproduce: []# service iptables start

Comment 1 Eric Hokanson 2006-02-22 13:58:17 UTC

Also noticed same problem occurs with the ipv6 module.

 --------------------- ModProbe Begin ------------------------ 

Errors inserting modules:
   ipv6 (/lib/modules/2.6.15.4/kernel/net/ipv6/ipv6.ko) :
      Cannot allocate memory  : 1 Time(s)

 ---------------------- ModProbe End -------------------------

Exact same problem (with iptables failing to load) on my system, kernel version
2.6.16.19

Comment 3 Stefaan 2006-09-10 04:29:54 UTC

After some testing, it seems the problem goes away for me when I change
  CONFIG_ALPHA_GENERIC
into
  CONFIG_ALPHA_MIATA (with additionally CONFIG_ALPHA_SRM).  

But CONFIG_ALPHA_GENERIC is supposed to work for miata as well, right?  So this
still remains a bug :(  Hopefully this piece of information helps in tracking it
down.

Comment 4 Natalie Protasevich 2008-04-16 21:51:26 UTC

Was the problem resolved since, or still needs workaround in #3?

Comment 5 Eric Hokanson 2008-04-30 14:32:01 UTC

We sent our Alpha off to retirement some time ago so I can no longer test.

Comment 6 Natalie Protasevich 2008-04-30 17:01:35 UTC

OK, please reopen if the problem confirmed with latest kernels.
