Things got stranger. The symptoms started to appear on other connections too (slashdot web for example). TCP bad packet count increased and no success was made. I did a reboot with the same kernel (2.4.19+bk of some state, 4. Aug probably) and it just started to work with the same kernel image.
I am seeing this exact same problem on 2.4.18+ipsec+grsecurity, though mine is on an Intel NIC..

Interrupt:10 This box was up for about 15 days without problems, and then started exhibiting this behavior of not seeing SYNACK's. Though this was happening to me on all attempts at making an outgoing TCP connection. My tcpdump was nearly identical to your earlier post. I rebooted it, and it has not had any problems with outgoing connections since(a whole 6 hours).

Now I will test and see if the symptoms appear again after some days.
That is where I am at too. If worst comes to worst, I will break out the memtest86 disk and see if it is in fact bad RAM causing this stuff.
btw... I am not subscribed to lkml, so please CC: me on any replies to this. Thanks. :)
