Hi,

I have the problem on client side and can not change server (FreeBSD 7.0). 
these patches does not change the situation (and they are probably not
supposed to do so, just giving it a try). After few minutes I got this on
the client with 2.6.28-rc6 with patches:

tcp   0   0 147.229.12.146:674          147.229.176.14:2049     FIN_WAIT2

Applying reverse e06799f958bf7f9f8fae15f0c6f519953fb0257c suggested by Ian
does help on the other side (with 2.6.27.4).

Bye
