This bug seems to be fixed in the latest stable kernel at kernel.org. I grepped the system.log for this log entry and it has been around for a while, so probably earlier kernel sources might also be affected: grep decoding\ error /var/log/syslog.log Aug 23 13:25:18 pluto ip_ct_ras: decoding error: out of bound Aug 23 13:43:16 pluto ip_ct_ras: decoding error: out of bound Aug 23 14:34:32 pluto ip_ct_ras: decoding error: out of bound Aug 23 18:38:21 pluto ip_ct_ras: decoding error: out of bound Aug 23 19:35:36 pluto ip_ct_ras: decoding error: out of bound Aug 23 21:42:12 pluto ip_ct_ras: decoding error: out of bound Aug 24 00:35:19 pluto ip_ct_ras: decoding error: out of bound Aug 27 05:57:46 pluto ip_ct_ras: decoding error: out of bound Aug 27 13:03:01 pluto ip_ct_ras: decoding error: out of bound Aug 27 13:03:02 pluto ip_ct_ras: decoding error: out of bound Sep 1 17:07:43 pluto ip_ct_ras: decoding error: out of bound Sep 2 07:33:14 pluto ip_ct_ras: decoding error: out of bound Sep 3 21:10:29 pluto ip_ct_ras: decoding error: out of bound Sep 3 21:58:43 pluto ip_ct_ras: decoding error: out of bound Sep 3 22:45:54 pluto ip_ct_ras: decoding error: out of bound Sep 9 02:03:31 pluto ip_ct_ras: decoding error: out of bound Sep 9 19:37:05 pluto ip_ct_ras: decoding error: out of bound Sep 12 14:53:29 pluto ip_ct_ras: decoding error: out of bound Sep 12 14:53:31 pluto ip_ct_ras: decoding error: out of bound Sep 12 16:30:44 pluto ip_ct_ras: decoding error: out of bound Sep 12 16:30:46 pluto ip_ct_ras: decoding error: out of bound Sep 12 18:13:57 pluto ip_ct_ras: decoding error: out of bound Sep 12 18:14:01 pluto ip_ct_ras: decoding error: out of bound Sep 12 23:41:58 pluto ip_ct_ras: decoding error: out of bound Sep 12 23:41:59 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:10 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:10 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:10 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:30 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:33 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:33 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:33 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:33 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:34 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:34 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:34 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:34 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:34 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:35 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:50:40 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:54:52 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:54:52 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:54:54 pluto ip_ct_ras: decoding error: out of bound Sep 18 05:54:57 pluto ip_ct_ras: decoding error: out of bound
gentoo-sources-2.6.17-r8 includes 2.6.17.13 so it must be something else...
well, since this bug does not appear in vanilla-sources 2.6.17.13 and gentoo-sources use the same kernel sources, it must be something related to the applied patchset, i.e. genpatches.
pluto is a nat gateway running on dynamic IP. The following is compiled into kernel: H.323 protocol support (EXPERIMENTAL) pluto connects some clients of the LAN to the Internet using DSL connection.
I looked thru gentoo-sources and since there are many changes to VIA I thought this might be useful: It is a VIA EPIA PD 6000 and the following output is from phpsysinfo Hardware Information Processors 1 Model VIA Samuel 2 CPU Speed 601.46 MHz Cache Size 64 KB System Bogomips 1205.15 PCI Devices 00:0f.0 Ethernet controller: VIA Technologies, Inc.

This is some kind of bug with "H.323 protocol support (EXPERIMENTAL)" unloading this module seams to help (haven't tried myself, but I've got such info).
Still reproducible on 2.6.19?
I can't say anything about it, since after finding out while using the same kernel-sources the bug is only with gentoo-sources, I switched to vanilla-sources and didn't have any problems since then.
OK, please reopen if you are interested in diagnosing further.
