Hi , On my SUN Ultra 60 I use OpenVPN in tcp-client mode. I use TAP devices to setup the tunnel. I noticed I receive these five messages whenever the tunnel is up. Kernel unaligned access at TPC[632208] tcp_transmit_skb+0x170/0x8a0 Kernel unaligned access at TPC[632210] tcp_transmit_skb+0x178/0x8a0 Kernel unaligned access at TPC[63251c] tcp_transmit_skb+0x484/0x8a0 Kernel unaligned access at TPC[632524] tcp_transmit_skb+0x48c/0x8a0 Kernel unaligned access at TPC[63252c] tcp_transmit_skb+0x494/0x8a0 They repeat every N seconds (depends on keepalive setting on server-side). After some rebooting I found out that the bug is introduced in 2.6.23.4. Up to and including 2.6.23.3 everything is fine. A 2.6.23.3 kernel with only this additional patch (from 2.6.23.4) 'TCP: Fix size calculation in sk_stream_alloc_pskb' http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.23.y.git;a=commit;h=9fcba4716e6ebbb0d7e0ec84bff6dd2c36c847b3 has the bug too.
