2.6.6-rc2 and newer cause trouble with amanda

[Andreas Sundstrom]

I have trouble upgrading from 2.6.5 to 2.6.6, I have narrowed it down by trying the different rc releases. Between 2.6.6-rc1 and 
2.6.6-rc2 something happens that make my amanda backups fail with the error [bad CONNECT response].

If I do nothing else than boot to 2.6.6-rc1 from rc2 it works so it seems to be somthing with the kernel that is causing the 
trouble, but I don't know how to investigate further.

This is the best debug info I've found so far.

Any ideas of how to investigat further? It seems that I'm the only one with this problem beacause I can't find any other posts about 
this. Unfortunately I don't have any other computers with tapedrives on them to try and reproduce the problem (although it seems to 
be about networking so a tapedrive might not be necessary to investigate).

Thanks for any help, I'm not on the list so feel free to CC me if you want a quick answer.

Let me know if I need to post more info, don't want to write a overly large e-mail to no use.
